The Adafruit Sparkle Motion Stick is part of our series of “Sparkle Motion” boards, which are our attempt to make the best small WLED-friendly smart LED driving board in the whole world. Our resident mermaid, firepixie makes a lot of projects with WLED, and she loves it! So, how can we make something powerful enough to drive advanced LED projects that need a compact design?

This version includes both the Sparkle Motion Stick and the enclosure, which is great if you want to protect your USB dongle from everyday usage, but note that it is not waterproof or weatherproof. There are three pieces: two snap over the PCB to capture it in place, and one can be used as a USB A port cap. We also like there’s a button lever - by default in WLED pin 0 is an on/off mode switcher, but you can program it to do other stuff.

The USB Stick version of the Sparkle Motion is a simpler version of our full-featured Sparkle Motion. It even fits into a low cost off-the-shelf case for protection.

• Power via USB Type A for up to 5V 2A input - you can use off-the-shelf USB battery packs for portable operation.
• 2 Amp resetting fuse to protect from over-current drive
• ESP32 mini module with built-in antenna port - the classic ESP32 has the best WLED support, even if we’d prefer the ‘S2 or ‘S3. Comes with 4 MB of flash, dual-core 240MHz Tensilica, WiFi, Bluetooth LE, and Bluetooth Classic support.
• USB-serial converter with auto-reset
• Two output signals plus 5V power and ground - both signal outputs are level shifted to 5V.
• Built-in I2S microphone for audio-reactive projects
• Built-in Infrared receiver on GPIO 10 for easy remote control integration
• User button on GPIO 0 which you can press even when its in the snap-on case
• Red built-in LED on pin 4
• Small built-in NeoPixel on pin 18
• Screw terminal blocks for no-solder connectivity

Compared to our larger Sparkle Motion board, this only supports 5V and doesn’t have a reset button, there are fewer outputs, and no breakout pads of I2C/GPIO connections for external accessories. Compared to our Sparkle Motion Mini, this has a USB A port so it’s 2A max power. It does have IR and built-in terminal blocks but does not have GPIO breakout pads.

While we recommend it for use with WLED, it will also work just fine as a compact ESP32 board for use with Arduino, ESP-IDF, MicroPython, CircuitPython, or any other ESP32-supported codebase.

We were catching up on a recent hackaday hackchat with eben upton and learned some fun facts: such as the DVI hack for the RP2040 was inspired by a device called the IchigoJam. we remember reading about this back when it was an LPC1114, now it uses an RP2040. well, we’re wrapping up the Metro RP2350 and lately we’ve been joking around that with DVI output and USB Host support via bit-banged PIO, you could sorta build a little stand-alone computer.

Well, one pear-green-tea-fueled-afternoon later we tried our hand at designing a ‘credit card sized’ computer - that’s 3.375” x 2.125”, about the same size as a business card and turns out there’s even a standard named for it: ISO/IEC 7810 ID-1.

Anyhow, with the extra pins of the QFN-80 RP2350B, we’re able to jam a ridonkulous amount of hardware into this shape:

• RP2350B dual 150MHz Cortex M33
• PicoProbe debug port
• 16 MB Flash + 8 MB PSRAM - the PSRAM will help when we want do do things like run emulations that we need to store in fast RAM access, and also let us use the main SRAM as the DVI video buffer.
• USB type C for bootloading/USB client
• Micro SD card with SPI or SDIO
• DVI output on the HSTX port
• I2S stereo headphone + mono speaker via the TLV320DAC3100
• 2-port USB type A hub for both keyboard and mouse or game controllers
• Chunky on-off switch
• Stemma QT I2C
• Stemma classic JST 3-pin
• EYESPI for TFT displays
• 5x NeoPixels
• 3x tactile switches
• 16-pin socket header with 10 A/D GPIO + 5V/3V/GND power pins.

The Raspberry Pi 500 is a fast, powerful computer built into a high-quality keyboard, for the ultimate compact PC experience. It features the same quad-core 64-bit Arm processor and RP1 I/O controller found in Raspberry Pi 5. With a one-piece aluminium heatsink built in for improved thermal performance, your Raspberry Pi 500 will run fast and smoothly even under heavy load, while delivering glorious dual 4K display output.

Normally you’d need to pick up a keyboard and other accessories to turn the Pi 5 into a functioning desktop - but since most keyboards have empty space in them, you can just cram the Pi 5 inside to make an all-in-one kit. Think of it like a modern Apple IIe, but super light and powerful.

There’s 3 USB ports, for adding USB mice, disk drives, or really any accessories that work with Linux. For video output, two HDMI ports can drive driving up to two monitors of any resolution up to 4k! There’s built in Bluetooth and WiFi for internet connectivity, or plug in an Ethernet cable for fast wired networking.

Hackers can rejoice - you still get the classic 2x20 IDC port that can be used to connect to a breadboard or HAT/PHat/Bonnet. To connect to a breadboard for wiring up buttons and LED, use our T-Cobbler! To connect to a Bonnet/HAT, we recommend a 2x20 IDC cable + Mini HAT Hacker (the cable plugs in at the top of the HAT hacker, giving you two spots for accessory HATs. Or our CYBERDECK Hat which has a nice angled connector to create a pop-up display

Adafruit Sparkle Motion - All-In-One WLED and xLights Board

We’re designing a board for using WLED - and we want to make like the bestest board in the whole world. Our resident mermaid, firepixie makes a lot of projects with WLED and she loves it! So how can we make something that will be powerful but not too bulky? Here’s some things we’re thinking about as the design starts to congeal like cranberry sauce:

• Power via USB Type C PD with a slide switch that selects between 5, 12 and 20V (24V pixels can usually run fine at 20V) OR via 2.1mm DC jack
• Low forward-voltage diodes so its good for up to 5A from either
• 5 Amp fuse to protect from over-current drive
• ESP32 mini module with built in or optionally wFL antenna port (the classic ‘32 has broad support even if we’d prefer the ‘S2 or ‘S3)
• Three output signal terminal block sets with power and ground for each - they’ll be level shifted to 5V.
• 6 GPIO breakout pads with a fourth level-shifted ouput, and 3 more GPIO plus power and ground.
• Built-in I2S microphone
• Built-in IR receiver
• Stemma QT I2C port to connect external sensors/OLED/etc
• Separate analog/digital input JST port for analog input, potentiometer, microphone or external IR receiver
• Compact enough you can use it for wearable projects - 1.3”x1.75” / 33mm x 45mm size with mounting holes

The Adafruit Sparkle Motion Mini is part of our series of “Sparkle Motion” boards, that are our attempt to make the best small WLED-friendly smart LED driving board in the whole world. Our resident mermaid, firepixie makes a lot of projects with WLED and she loves it! So how can we make something that will be powerful enough to drive advanced LED projects that need a compact design?

The Mini version of the Sparkle Motion is a simpler version of our full-featured Sparkle Motion, we give up the high voltage support and built in IR receiver, in order to make it under 1 square inch in size! By using a 4-layer board and double-sided assembly we’ve put together this feature set:

• Power via USB Type C for up to 5V 4A input - you can use off-the-shelf USB battery packs for portable operation.
• 4 Amp resetting fuse to protect from over-current drive
• ESP32 mini module with built in antenna port - the classic ESP32 has the best WLED support even if we’d prefer the ‘S2 or ‘S3. Comes with 4 MB of flash, dual core 240MHz Tensilica, WiFi, Bluetooth LE and Bluetooth Classic support.
• USB-serial converter with auto-reset
• Two output signals plus 5V power and ground - both signal output are level shifted to 5V. These are on 0.1” spaced breakout pads. To keep the design slim we don’t include terminal blocks pre-soldered, but we do stock the matching blocks if you want them
• Extra 2x3 0.1” breakout pads with 4 more GPIO plus 3V power and ground.
• Built-in I2S microphone
• Stemma QT I2C port to connect external sensors/OLED/etc
• User button on GPIO 0 plus Reset button
• Red built-in LED on pin 12
• Small built-in NeoPixel on pin 18
• Separate analog/digital input JST port for analog input, potentiometer, microphone or external IR receiver on pin 13
• Compact enough you can use it for wearable projects - 1.2”x0.8” / 30mm x 20mm size with mounting holes

While we recommend it for use with WLED, it will also work just fine as a compact ESP32 board for use with Arduino, ESP-IDF, MicroPython, CircuitPython or any other ESP32 supported codebase.

Note that unlike the classic Sparkle Motion board, we don’t include terminal blocks pre-soldered to keep the board very slim. We do stock the matching blocks if you want them, a small amount of soldering is required to attach them. Also, unlike the bigger version, we dropped the on-board IR receiver - however its easy to add one by plugging in a JST SH 3-pin socket cable and slotting in an IR receiver module.

The Workshop System is an analogue modular synth and a powerful audio computer – designed to be useful and open:

• A genre-neutral toolkit, a little box of ways to make and manipulate music and sound.
• A patchable, hackable, code-able modular synth that can be used in many different ways.
• A system that works with things you already have. Plug in your phone, a drum machine, a laptop, guitar pedals or a microphone.
• A computer that uses tiny program cards that are completely hackable. Anyone who writes code can make, share, sell their creations — sequencers, effects, interfaces.

The Workshop System arrives as a DIY kit which will take a few hours to put together. All the tiny SMD components have already been soldered for you, so the build process consists mainly of soldering jack sockets, potentiometers and switches while following the build guide: musicthing.co.uk/Workshop_System_Build_Guide

The Workshop System kit includes:

• All hardware required to build the Workshop System (PCBs, Front & Back Panel, components, knobs, buttons etc.)
• A rugged hard plastic carry case for easy portability with internal foam cutout to keep the system protected
• 2 x audio adaptor cables to plug a guitar pedal into the Stompbox section of the Workshop System – the cables are 3.5mm (1/8″) Minijack to 6.35mm (1/4″) Jack
• A 20cm DC barrel cable for directly powering a guitar pedal from the front of the Workshop – 9V (centre-negative)
• A keyring and set of 4 x Program Cards to get started using the computer section. The included cards are: a Turing Machine (random looping sequencer), a lush digital Reverb, a MIDI to CV converter and a Blank card to fill with another function of your choice – or to explore creating programmes of your own. More blank cards can be found HERE

The kit does not include:

• Eurorack patch cables – we figure that many users of modular synths already have patch cables lying around – but if you’re just starting out and would like a set of short patch cables then we have a cable set available HERE
• A power cable – The Workshop System has two power options: The easiest way is via USB-C PD power, but you can also use a regular 15-25v DC barrel connection. The system will happily run from battery powerbanks and laptop adaptors. We feel that there are already enough USB-C cables in the world. If you do want to source a USB-C wallwart then we recommend using one that’s rated at 30W or above.

The Workshop System has 14 modules:

• 2 x SineSquare Oscillators Simple vintage-style oscillators made of 1970s tech.
• 2 x Humpback Filters Similarly vintage-style filters, designed by Philip Goulding of God’s Box.
• 2 x Slopes These work as attack/decay envelopes, LFOs and portamento generators.
• Computer Is a multi-function module with knobs, a switch and audio, CV and pulse ins and outs. Initially, the system comes with a USB MIDI card, a Turing Machine sequencer and a Reverb card. A community of programmers are creating more cards.
• Stereo In takes a 3.5mm stereo input and boosts it to modular level.
• Ring Mod is a great-sounding ring modulator, connected to the two sines. It also works as a simple VCA.
• Stompbox is an interface for guitar pedals, with blend and feedback controls to make boring pedals more interesting. There’s a 9v power outlet for pedals below this module.
• Amplifier contains two simple circuits. One is connected to a piezo contact mic behind the panel, the other is the transistor-based input circuit from a MiniMoog. In other words, a Mikrophonie and a Mini Drive.
• 4 Voltages is a minimum viable keyboard: four voltage outputs, one knob, four pushbuttons. More fun to play with than to explain.
• Mix a simple output mixer, with two stereo channels, two mono channels and a powerful headphone amp / line out.
• PSU behind the panel is a power supply that runs on USB-C PD power or professional 15-25v barrel connectors. It works from battery powerbanks and laptop adaptors, most likely something you’ve already got at home.

Raspberry Pi Pico 2W is Raspberry Pi Foundation’s update to their popular RP2040-based wireless ico board, now built on RP2350: their new high-performance, secure microcontroller. With a higher core clock speed, double the on-chip SRAM (512KB), double the on-board flash memory (4MB!), more powerful Arm M33 cores, new security and low-power features, and upgraded interfacing capabilities, the Raspberry Pi Pico 2 delivers a significant performance and feature boost while retaining hardware and software compatibility with earlier members of the Raspberry Pi Pico series.

The unique dual-core, dual-architecture capability of RP2350 allows users to choose between a pair of industry-standard Arm Cortex-M33 cores and a pair of open-hardware Hazard3 RISC-V cores. You can use either Arm or RISC-V cores, so this is a great way to dabble in RISC-V development with an affordable board that has lots of peripherals. The M33 has an FPU, and is ‘basically’ 2x as fast as the M0+ of the RP2040 when we speed-tested it.

Not only is the Pico 2 twice as fast, it has twice as much RAM, 520KB compared to 264KB. The Pico also has twice as much FLASH memory, 4MB instead of 2MB, which will make it a much better board for CircuitPython usage where the internal memory is used to store files. There’s also one more PIO blocks (3 blocks with 4 state machines apiece, rather than 2) so you can do even more pin twiddling at once. For folks who want to use the RP2350 to generate high frequency output signals like DVI display output, you can use the HSTX (high speed transmission) peripheral rather than PIO.

For customers who wanted a more secure microcontroller for product design, the RP2350 provides a comprehensive security architecture, built around Arm TrustZone for Cortex-M, and incorporating signed boot, 8KB of antifuse OTP for key storage, SHA-256 acceleration, a hardware TRNG, and fast glitch detectors. These features, including the secure boot ROM, are extensively documented and available to all users without restriction: this transparent approach, which contrasts with the “security through obscurity” offered by legacy vendors, allows professional users to integrate RP2350, and Raspberry Pi Pico 2, into products with confidence.

Programmable in C / C++ and CircuitPython/MicroPython, and with detailed documentation, Raspberry Pi Pico 2 is the ideal microcontroller board for enthusiasts and professional developers alike. It makes an excellent upgrade to the RP2040, with lots of back-compatibility and some excellent upgrades.

Please note: The Pico 2Wcomes with the A2 version of the RP2350, which is affected by the E9 erratum. This erratum affects some uses of GPIO and PIO such as high-impedance inputs and the internal pulldowns. You may need to use 8.2K or smaller resistors if pull-downs are required. At this time, Sept 9 2024, there is no other version of the RP2350 available - only the A2 version.

A top of the line Pirate-brand RP2350 microcontroller with 16MB of flash memory, 8MB of PSRAM, USB-C, Qw/ST and 2.4GHz wireless / Bluetooth.

We adore the versatility and value of Raspberry Pi Pico but we also enjoy a souped up RP2350 board with all the extras baked in. With Pimoroni Pico boards, we’ve tried to cram in as much extra functionality as we possibly can whilst keeping to the original Pico footprint to maintain compatibility with existing Pico addons.

Pimoroni Pico Plus 2 W is powered and programmable via USB-C and comes with an upgraded 8MB RAM, 16MB of flash storage and easy to read pin labels. The ‘W’ version is also equipped with a Raspberry Pi RM2 module, which gives it 2.4 GHz wireless and Bluetooth connectivity, woohaa!

It’s super easy to connect up to things without soldering, with a Qwiic/STEMMA QT connector (for adding I2C sensors and breakouts), and a debug connector (for if you like to program using a SWD debugger). We’ve also added a reset button, and a BOOT button - this can also be used as a user switch.

Features

• Powered by RP2350B (Dual Arm Cortex M33 running at up to 150MHz with 520KB of SRAM)
• 16MB of QSPI flash supporting XiP
• 8MB of PSRAM
• Raspberry Pi RM2 module provides 2.4GHz wireless and Bluetooth connectivity
• USB-C connector for power, programming, and data transfer
• Qw/ST (Qwiic/STEMMA QT) connector for attaching breakouts
• 3 pin debug connector (JST-SH)
• Reset and BOOT buttons (the BOOT button can also be used as a user button)
• User LED indicator
• On-board 3V3 regulator (max regulator current output 600mA)
• Input voltage range 3V - 5.5V
• Compatible with Raspberry Pi Pico add-ons
• Measurements: approx 53mm x 21mm x 9mm (L x W x H, including connectors)

About RP2350

The RP2350 chip is the Double Quarter Pounder & Fries to the RP2040’s Double Cheeseburger and can have one or more RISC-V burgers instead of either of the M33 ARMs, to stretch the metaphor.

In addition to the modern M33 ARM cores, there are sides of: more PIO capability, a variety of low power states for sipping electrons, a whole security system and some sprinklings of specialist digital video circuits to offload DVI/HDMI output.

You can expect a tasty boost in performance - our “real world” MicroPython tests are running up to 2x faster compared to RP2040, and floating point number crunching in C/C++ is up to 20x faster. The extra on-chip RAM will make a big difference when performing memory intensive operations (such as working with higher resolution displays) and even more can be added thanks to external PSRAM support.

RP2350 comes in two flavours - A (standard) and B (all the pins). The B chip has a stonking 48 usable GPIO pins, including 8 ADCs and 24 PWMs, and features on some of our new products.

A postage stamp sized RP2350 development board with a USB-C connection, perfect for portable projects, wearables, and embedding into stuff.

While we love the Raspberry Pi Pico we also wanted something smaller and with a bunch more flash on board. Introducing the Tiny 2350 - a teeny tiny powerhouse with the chops to realise truly ambitious projects.

Programmable via USB-C, Tiny 2350 comes with 4MB of flash storage on board. The board is designed with castellated pads to allow it to be directly soldered onto a PCB (or you can attach pin headers to hook it up on a breadboard or connect things to it directly with wires). We’ve also managed to fit in a programmable RGB LED, a reset button, a Qw/ST connector for connecting up I2C devices and some clever circuitry that lets you use the boot button as a user controllable switch.

It’s compatible with firmware built for the Raspberry Pi Pico 2 but offers a reduced number of pins due to its size. You can even run MicroPython on it!

Features

• Powered by RP2350A (Dual Arm Cortex M33 running at up to 150MHz with 520KB of SRAM)
• 4MB of QSPI flash supporting XiP
• USB-C connector for power, programming, and data transfer
• User controllable RGB LED
• Qw/ST (Qwiic/STEMMA QT) connector for attaching breakouts
• Twelve IO pins (including four 12-bit ADC channels)
• Reset and BOOT buttons (the BOOT button can also be used as a user button)
• On-board 3V3 regulator (max regulator current output 300mA)
• Input voltage range 3V - 5.5V
• Programmable with C/C++ or MicroPython
• Dimensions: approx 22.9 x 18 x 5.8mm (L x W x H, including the USB-C port)

About RP2350

The RP2350 chip is the Double Quarter Pounder & Fries to the RP2040’s Double Cheeseburger and can have one or more RISC-V burgers instead of either of the M33 ARMs, to stretch the metaphor.

In addition to the modern M33 ARM cores, there are sides of: more PIO capability, a variety of low power states for sipping electrons, a whole security system and some sprinklings of specialist digital video circuits to offload DVI/HDMI output.

You can expect a tasty boost in performance - our “real world” MicroPython tests are running up to 2x faster compared to RP2040, and floating point number crunching in C/C++ is up to 20x faster. The extra on-chip RAM will make a big difference when performing memory intensive operations (such as working with higher resolution displays) and even more can be added thanks to external PSRAM support.

RP2350 comes in two flavours - A (standard) and B (all the pins). The B chip has a stonking 48 usable GPIO pins, including 8 ADCs and 24 PWMs, and features on some of our new products.

A minimal but powerful RP2350 breakout board modelled on a Pin Grid Array, with the maximum exposed pins crammed into the smallest possible space.

PGA2350 is a compact RP2350 breakout designed to be embedded in projects where space is limited. It contains the components necessary to run the mighty RP2350B chip (that’s the crystal, regulator and essential support circuits), a beefy 8MB of PSRAM and a prodigious 16MB of flash storage. Note that it has no LEDs, buttons or USB connectors - you’ll need to attach your own USB connector to be able to program it.

All this drastic pruning means you get a small 25.4mm square footprint and a lot of exposed RP2350 pins to play with. 48 of them can be used as general purpose I/O (that’s eighteen more I/O than on a Raspberry Pi Pico!) and 8 are ADC-equipped. We’ve even managed to squeeze in some tiny pin labels to help identify them.

Header pins are sold separately - you can use standard Pico pin headers (though bear in mind you’ll need 64 pins if you want to populate it fully).

Features

• Powered by RP2350B (Dual Arm Cortex M33 running at up to 150MHz with 520KB of SRAM)
• 16MB of QSPI flash supporting XiP
• 8MB PSRAM (CS wired to GP47 via cuttable trace)
• Crystal oscillator
• On-board 3V3 regulator (max regulator current output 300mA)
• 64 pins, arranged with 2.54mm (0.1”) spacing in a Pin Grid Array
• 48 multi-function General Purpose IO (8 can be used for ADC)
• 6 GND pins
• Input voltage range 3V - 5.5V (on VB pin only)

The ESP32-S3-DevKitC-1 is an entry-level development board equipped with ESP32-S3-WROOM-1, a general-purpose Wi-Fi + Bluetooth LE MCU module that integrates complete Wi-Fi and Bluetooth LE functions. This version is equipped with the ESP32-S3-WROOM-1 (PCB antenna) with 16MB Flash and no PSRAM.

Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S3-DevKitC-1 on a breadboard. We particularly like that there’s a debug UART/USB port and a separate native USB port, so you can upload/debug/USB all at once.

At the core of the module is an ESP32-S3FN8, an Xtensa? 32-bit LX7 CPU that operates at up to 240 MHz. You can power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for changes or crossing of thresholds.

ESP32-S3FN8 integrates a rich set of peripherals including SPI, LCD, Camera interface, UART, I2C, I2S, remote control, pulse counter, LED PWM, USB Serial/Jtag, MCPWM, SDIO host, GDMA, TWAI? controller (compatible with ISO 11898-1, i.e. CAN Specification 2.0), ADC, touch sensor, temperature sensor, timers, and watchdogs, as well as up to 45 GPIOs. It also includes a full-speed USB 1.1 On-The-Go (OTG) interface to enable USB communication

There are three mutually exclusive ways to provide power to the board:

• USB-to-UART Port and ESP32-S3 USB Port (either one or both), default power supply (recommended)
• 5V and G (GND) pins
• 3v3 and G (GND) pins

The Stamp was created to allow you to use the Raspberry Pi RP2350B in your designs without having to solder small-pitch QFN chips or worry about lots of external circuitry.

The RP2350 Stamp XL is partially pad-compatible with the smaller Stamps. The left-side pads as well as half of the top and bottom ones are exactly the same.

All you need to get you started is a 5V supply or a LiPo battery. The Stamp will take care of the charging and switching the power sources.

The castellated edges with 2mm pitch can be hand-soldered directly to a Carrier board, used with pin headers for more flexibility, or connected without soldering using FlexyPins, which are spring connectors designed for modules with castellated edges. You can find footprints for many PCB programs here.

We were also able to squeeze in two new functional pads: an LDO EN pad, connected to the LDOs EN signal, and a BAT STAT, connected to the LiPo charger’s STAT pin.

At only 1 by 1? inch, the Stamp XL packs a lot of features:

• 16MB of FLASH
• 500mA 3.3V LDO
• All 48 GPIOs broken out
• A footprint for a second QSPI FLASH/PSRAM
• Footprints for SWD and UART JST connectors, pin-compatible with the Raspberry Pi Debug Probe
• LiPo supply and charging circuit (with charging LED)
• USB broken out
• SWD broken out
• Reset Button
• Bootsel Button
• 12MHz crystal

and of course, everything that comes with the Raspberry Pi RP2350 itself:

• Dual core ARM Cortex-M33 or Hazard3 @ 150MHz
• 520kB SRAM
• 2 UARTs
• 2 SPIs
• 2 I2Cs
• 24 PWM channels
• 12 PIO state machines
• 1 HSTX peripheral
• USB with Host and Device support

The RP2350 comes with a pre-programmed ROM UF2 Bootloader, by pulling the BOOTSEL pin low and resetting, or by double-pressing the RESET button (if the FW supports it), you can upload new firmware using the USB disk drive.

The CircuitPython firmware for the Stamp comes with a built-in board files for the Carriers, for example you can access the RP2040 Stamp Carrier pins and interfaces by using import stamp_carrier_board as board. See here for all the available Carrier board files.

Raspberry Pi Pico 2 is Raspberry Pi Foundation’s update to their popular RP2040-based Pico board, now built on RP2350: their new high-performance, secure microcontroller. With a higher core clock speed, double the on-chip SRAM (512KB), double the on-board flash memory (4MB!), more powerful Arm M33 cores, new security and low-power features, and upgraded interfacing capabilities, the Raspberry Pi Pico 2 delivers a significant performance and feature boost while retaining hardware and software compatibility with earlier members of the Raspberry Pi Pico series.

The unique dual-core, dual-architecture capability of RP2350 allows users to choose between a pair of industry-standard Arm Cortex-M33 cores and a pair of open-hardware Hazard3 RISC-V cores. You can use either Arm or RISC-V cores, so this is a great way to dabble in RISC-V development with an affordable board that has lots of peripherals. The M33 has an FPU, and is ‘basically’ 2x as fast as the M0+ of the RP2040 when we speed-tested it.

Not only is the Pico 2 twice as fast, it has twice as much RAM, 520KB compared to 264KB. The Pico also has twice as much FLASH memory, 4MB instead of 2MB, which will make it a much better board for CircuitPython usage where the internal memory is used to store files. There’s also one more PIO blocks (3 blocks with 4 state machines apiece, rather than 2) so you can do even more pin twiddling at once. For folks who want to use the RP2350 to generate high frequency output signals like DVI display output, you can use the HSTX (high speed transmission) peripheral rather than PIO.

For customers who wanted a more secure microcontroller for product design, the RP2350 provides a comprehensive security architecture, built around Arm TrustZone for Cortex-M, and incorporating signed boot, 8KB of antifuse OTP for key storage, SHA-256 acceleration, a hardware TRNG, and fast glitch detectors. These features, including the secure boot ROM, are extensively documented and available to all users without restriction: this transparent approach, which contrasts with the “security through obscurity” offered by legacy vendors, allows professional users to integrate RP2350, and Raspberry Pi Pico 2, into products with confidence.

Programmable in C / C++ and CircuitPython/MicroPython, and with detailed documentation, Raspberry Pi Pico 2 is the ideal microcontroller board for enthusiasts and professional developers alike. It makes an excellent upgrade to the RP2040, with lots of back-compatibility and some excellent upgrades.

Choo! Choo! This is the RP2350 Metro Line, making all station stops at “Dual Cortex M33 mountain”, “520K RAM round-about” and “16 Megabytes of Flash town” and available with a bonus stop at “8 Megabytes of PSRAM village”. This train is piled high with hardware that complements the Raspberry Pi RP2350 chip to make it an excellent development board for projects that want Arduino-shape-compatibility or just need the extra space and debugging ports.

• RP2350 main chip, 150MHz clock, 3.3V logic
• 16 MB of QSPI flash for program storage
• Available with 8 MB of QSPI PSRAM for extra dynamic memory
• 24 GPIO, 8 of which are also analog inputs
• Micro SD card socket wired up for SPI interfacing, also has extra pins connected for advanced-user SDIO interfacing (note that there’s no released usage code for SDIO in Arduino/Python, so this is a super-cutting-edge setup)
• Onboard RGB NeoPixel
• Onboard #13 LED
• Stemma QT port for I2C peripherals and sensors
• 22-pin 3-lane differential HSTX FPC port with ‘Pi 5’ compatible pinout
• Reset and Boot buttons on PCB edge
• Pico Probe debug port - 3 pin JST SH compatible
• USB Type C power and data
• 5.5mm / 2.1mm DC jack for 6-12VDC power
• On/off switch for DC jack
• GPIO pin numbers match classic Arduino pins
• RX / TX switch for swapping D0 and D1 locations

You may be wondering about the RX-TX switch: we added this because traditional Arduino board start counting the GPIO for the digital pins with 0-7 and then 8-13. However, the D0/D1 pins are also traditionally the hardware UART Serial1, where D0 is Rx and D1 is Tx. On the RP2350, however, the UART pins are the other around: D0 is Tx and D1 is Rx. Thus a DPDT switch: flip one way to have the GPIO go in order of 0-7, flip the other way to have the logical locations of the hardware UART correct but now the pin order is 1, 0, 2, 3..7. Of course, it’s also handy if, like us, you often swap the pins - now you don’t need to require or cut/solder traces!

Inside the RP2350 is a ‘permanent ROM’ USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar - we use the technique on all our native-USB boards. Just note you don’t double-click reset instead hold down BOOTSEL during boot to enter the bootloader!

There is great C/C++ support, unofficial (but really good) Arduino support, an official MicroPython port, and a CircuitPython port! We of course recommend CircuitPython because we think it’s the easiest way to get started and it has support with most of our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.

While the RP2350 has lots of onboard RAM, it does not have built-in FLASH memory. Instead, that is provided by the external QSPI flash chip. On this board there is 16 MB, which is shared between the program it’s running and any file storage used by MicroPython or CircuitPython. When using C/C++ you get the whole flash memory, if using Python you will have about 14 MB remaining for code, files, images, fonts, etc.

RP2350 Chip features:

• Dual ARM Cortex-M33 with floating point unit or Dual RISC-V @ 150MHz
• 520 kB on-chip SRAM
• 8 kB of one-time-programmable (OTP) memory.
• Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus

RP2350 flies high with the Feather format - now you can use any FeatherWings with this battery-powered dev board. It comes with 8MB of flash, 22pin HSTX output port, Stemma QT, debug SWD, and optional PSRAM spot. It’s our first RP2350 board and we crammed a ton of goodies into our classic Feather format. It’s an excellent starter board to go along with your Pico 2.

The RP2350 is Raspberry Pi’s second microcontroller chip following their breakout-hit the RP2040. Building on their success, the RP2350 upgrades the dual M0 core to dual M33 cores with 150 MHz clock rate. The M33 is a much newer Arm chipset, we’ve found that firmware runs about twice as fast. Especially given that we now have hardware floating point support. Also, the RP2350 has twice as much SRAM: 520KB instead of 264KB which means that micropython/circuitpython runs great and also IoT projects that need a lot of memory buffer space will run better. Other improvements include, 3 PIO blocks instead of 2, TrustZone secure boot, and a special High Speed Transmit (HSTX) peripheral that drives 4 lanes of differential data transmission such as DVI output without needing to overclock or use PIO.

For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 24 PWM channels, each pin has a channel it can be set to (ditto on the pinout).

Feather RP2350 HSTX Specifications:

• Measures 2.0” x 0.9” x 0.28” (50.8mm x 22.8mm x 7mm) without headers soldered in
• Light as a (large?) feather - 5 grams
• RP2350 32-bit Cortex M33 dual core running at 150 MHz @ 3.3V logic and power
• 520 KB RAM + 8 KB OTP memory
• 8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code storage. No EEPROM
• Optional spot for SOIC PSRAM chip with chip select line on GPIO 8
• Tons of GPIO! 29 x GPIO pins with following capabilities:
  • 21 GPIO available on the Feather header pins, 8 more ‘consecutive’ GPIO available on the HSTX connector (you don’t have to use them with the HSTX peripheral)
  • Four 12-bit ADCs (one more than Pico 2)
  • Two I2C, Two SPI, and two UART peripherals, we label one for the ‘main’ interface in standard Feather locations
  • 24 x PWM outputs - for servos, LEDs, etc
• Built-in 200mA+ lipoly charger with charging status indicator LED. For non-rechargeable battery usage the charger can be disabled by cutting a jumper trace on the back.
• Pin #7 red LED for general purpose blinking
• RGB NeoPixel for full-color indication.
• On-board STEMMA QT connector that lets you quickly connect any Qwiic, STEMMA QT or Grove I2C devices with no soldering!
• Both Reset button and Bootloader select button for quick restarts (no unplugging-replugging to relaunch code)
• 3.3V Power/enable pin
• Pico Probe 3-pin JST SH connector for SWD debugging
• 4 mounting holes
• 12 MHz crystal for perfect timing.
• 3.3V regulator with 500mA peak current output
• USB Type C connector lets you access built-in ROM USB bootloader and serial port debugging

Please note: The Adafruit Feather RP2350 HSTX comes with the A2 version of the RP2350, which is affected by the E9 erratum. This errata affects some uses of GPIO and PIO such as high-impedance inputs and the internal pulldowns. You may need to use 8.2K or smaller resistors if pull-downs are required. At this time, Sept 9 2024, there is no other version of the RP2350 available - only the A2 version.

At the Feather’s heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the Raspberry Pi Pico. This chip has a whopping 8MB of onboard QSPI FLASH and 264K of RAM! This makes it great for buffering and processing data before writing it to the SD card.

To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built-in battery charging. You don’t need a battery, it will run just fine straight from the USB Type C connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when it’s available.

Here’re some handy specs! You get:

• Measures 2.0” x 0.9” x 0.28” (50.8mm x 22.8mm x 7mm) without headers soldered in
• Light as a (large?) feather - 6.3 grams
• RP2040 32-bit Cortex M0+ dual core running at ~133 MHz @ 3.3V logic and power
• 264 KB RAM
• 8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code storage. No EEPROM
• Tons of GPIO! 21 x GPIO pins with following capabilities:
  • Four 12-bit ADCs (one more than Pico)
  • Two I2C, Two SPI, and two UART peripherals, we label one for the ‘main’ interface in standard Feather locations
  • 16 x PWM outputs - for servos, LEDs, etc
• Built-in 200mA+ lipoly charger with charging status indicator LED
• Pin #13 red LED for general purpose blinking
• RGB NeoPixel for full-color indication.
• MicroSD card holder for adding as much storage as you could possibly want for reading or writing. Connected to the ‘second’ SPI port on pins 18, 19, 20 and card select on 23. Optional card detect line can be connected to pin 15. For advanced hackers who want to use 4-bit SDIO, we connect DAT1 and DAT2 to 21 and 22 - note we do not have Arduino or CircuitPython code for this mode.
• On-board STEMMA QT connector that lets you quickly connect any Qwiic, STEMMA QT or Grove I2C devices with no soldering!
• Both Reset button and Bootloader select button for quick restarts (no unplugging-replugging to relaunch code)
• USB Type C connector lets you access built-in ROM USB bootloader and serial port debugging
• 3.3V Power/enable pin
• 4 mounting holes
• 12 MHz crystal for perfect timing.
• 3.3V regulator with 500mA peak current output

Comes assembled and tested, with some header. You’ll need a soldering iron to attach the header for installing onto your Feather. Stacking headers will let you put another FeatherWing on top. Lipoly battery, MicroSD card, and USB cable not included (but we do have lots of options in the shop if you’d like!)

Please note that the pictured board is a Nano 33 BLE Sense Rev2. This build works with both the Nano 33 BLE Rev2 and the Sense Rev2.

This compact and reliable NANO board is built around the u-blox NINA-B306 module, based on the Nordic nRF52840 and containing a powerful Cortex-M4F core. Its architecture, fully compatible with Arduino IDE Online and Offline, has a 9-axis Inertial Measurement Unit (IMU) and a reduced power consumption compared to other same size boards. This allows the design of wearable devices and movement sensing projects that need to communicate to other devices at a close range. Arduino Nano 33 BLE Rev2 is also ideal for automation projects thanks to the multiprotocol BT 5.0 radio.

The Arduino NANO 33 BLE Sense Rev2 adds an APDS-9960 light, colour, gesture and proximity sensor; an LPS22HB pressure and temperature sensor; an HS3003 humidity sensor; and a MP34DT06JTR microphone.

To use this board with CircuitPython you must replace the existing bootloader with the Adafruit UF2 bootloader. You need to restore the original bootloader to use the board again with Arduino.

Usage Notes

The serial port on the ESP32-MB adapter which usually ships with these boards has the Serial Request-To-Send (RTS) hardware flow-control line physically connected to the ESP32 Reset (RST) pin, and it also has the Serial Data-Terminal-Ready (DTR) hardware flow-control line physically connected to the ESP32 GPIO pin.

This allows software which knows this (e.g. Arduino) to automatically perform hardware resets over the serial port by pulsing the RTS-line, and to automatically perform firmware updates by holding the DTR line low while pulsing the RTS line.

Unfortunately, many serial emulators and even some python libraries which communicate via Serial ports will typically set the state of one of both of these hardware flow control lines - this means that your ESP32-CAM might not be able to boot or be used by some software. Notable examples include Thonny, ampy, pyboard, and Windows version of Python itself*

* The work-around for Windows python is to first create the serial port object, without specifying which port to use - this bypasses the Python windows bug which always sets the RTS/DTR pins. You can then tell the serial object which port, and set the RTS/DTR pins as you like.

It’s half USB Key, half TRRS breakout… it’s the Adafruit TRRS Trinkey specifically designed for Assistive Technology hackers and creators as a simple and low cost, but also flexible and extendable AT device.

Many AT interface devices use 3.5mm audio jacks to create switches or variable inputs - often mono TS or stereo TRS plugs. On the TRRS Trinkey, we connect all 6 pins of a ‘switched’ TRRS jack - tip, ring 1, ring 2, sleeve and the tip switch plus ring 1 switch - to 6 GPIO pins on the microcontroller. That means we can not only detect when plugs are inserted but can change which pins are input, ground or even 3V power. With the use of a stereo/mic splitter, we can have up to 3 simple switches, or two analog potentiometers, or one of each! We particularly like this jack because it has two through-hole contacts near the opening for a good mechanical connection.

The PCB is designed to plug into any USB A port on a computer or laptop. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to a NeoPixel LED. A reset button lets you enter bootloader mode if necessary. The microcontroller can be programmed easily thanks to the UF2 bootloader and CircuitPython: simply drag-n-drop new code on.

The SAMD21 can run CircuitPython or Arduino nicely. Over the USB connection, you can have serial, MIDI, or HID keyboard/mouse connectivity. Because its a fully programmable chip, it’s possible to customize the keyboard or mouse commands executed on each button, or even set up chording patterns.

Features:

• ATSAMD21E18 32-bit Cortex M0+ - 48 MHz 32-bit processor with 256KB Flash and 32 KB RAM
• Native USB supported by every OS - can be used in Arduino or CircuitPython as a USB serial console, MIDI, Keyboard/Mouse HID, and even a little disk drive for storing Python scripts. Can act like a keyboard to phones or tablets with a USB adapter cable.
• Can be used with Arduino IDE or CircuitPython
• TRRS Jack with two switches on tip and ring 1. All 6 contacts connect to analog-input capable GPIO pins
• One RGB NeoPixel LED
• STEMMA QT port with JST SH 4-pin compatible connector - can be used to add I2C devices, or two more inputs. Note CircuitPython may not have enough memory for large chip drivers.
• Reset switch to start your project code over or enter bootloader mode
• Open Source Hardware so you have full control over your assistive tech!

The ESP32-C6 is Espressif’s first Wi-Fi 6 SoC integrating 2.4 GHz Wi-Fi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. It brings the goodness you know from the low-cost C3 series and improves it with Zigbee/802.15.4 at 2.4Ghz. That means it could make for great Matter development hardware!

We took our Feather ESP32-S2 and swapped out the ‘S2 for a C6. Plus some re-routing and here’s what we’ve got: a C6 Feather with lots of GPIO, lipoly charging and monitoring with the MAX17048, NeoPixel, I2C Stemma QT port, and a second low-quiescent LDO for disabling the I2C and NeoPixel when we want ultra-low power usage - as low as 17uA in deep sleep.

One thing to watch for is that, like the C3, the C6 does not have native USB. It does have a ‘built in’ USB Serial core that can be used for debugging, but it cannot act like a mouse, keyboard, or disk drive. That means if you are running CircuitPython you will need to use WiFi, Bluetooth or WebSerial for transferring files back and forth rather than drag-and-dropping to a drive. Ditto for the bootloader side, this chip cannot run UF2.

It’s half USB Key, half temperature-humidity sensor… it’s the Adafruit SHT41 and SHT45 Trinkey boards. We wanted to make it super-easy to add one of our most popular combination environmental sensors to any computer with a USB A port.

The PCB is designed to slip into any USB A port on a computer or laptop. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to a NeoPixel LED. Another pin is used as a capacitive touch input on the end. A reset button lets you enter bootloader mode if necessary. That’s it!

The SAMD21 can run CircuitPython or Arduino nicely - both have existing SHT4x, NeoPixel, and our FreeTouch (capacitive touch) libraries. Over the USB connection, you can have serial, MIDI, or HID connectivity.

The SHT41 sensor is the fourth generation of I2C temperature and humidity sensor from Sensirion. (They started at the SHT10 and reached the top!). The SHT41 has an excellent ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2 °C typical accuracy from 0 to 75 °C. The reported temperature may be a few degrees higher than ambient due to self-heating.

The SHT45 sensor is the fourth generation (started at the SHT10 and worked its way up to the top!). The SHT45 has an excellent ±1.0% typical relative humidity accuracy from 25 to 75% and ±0.1°C typical accuracy from 0 to 75 °C. The reported temperature may be a few degrees higher than ambient due to self-heating.

The SHT41 or SHT45 Trinkey is perfect for simple projects that want to read the ambient temperature and humidity without extra wiring, soldering, drivers, or complex software. We even ship the board pre-programmed with code that will print a unique serial number, the temperature, humidity, and touch sensor over a serial/COM port in CSV (comma-separated value) format so you can use it immediately. If you need to measure farther than the computer port, simply use any USB A extension cable.

If you don’t need high precision, save a few $ with the SHT41 Trinkey, which has ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2°C typical accuracy from 0 to 75 °C.

We think it’s just an adorable little board. It’s small, durable, and inexpensive enough to be a first microcontroller board or an inspiration for advanced developers to make something simple and fun.

• ATSAMD21E18 32-bit Cortex M0+ - 48 MHz 32-bit processor with 256KB Flash and 32 KB RAM
• Native USB supported by every OS - can be used in Arduino or CircuitPython as a USB serial console, MIDI, Keyboard/Mouse HID, and even a little disk drive for storing Python scripts.
• Can be used with Arduino IDE or CircuitPython
• One RGB NeoPixel LED
• One Capacitive Touchpad
• SHT41 or SHT45 Temperature + Humidity sensor with thermal-isolation cutout

A20-OLinuXino-LIME2 looks similar to both A20-OLinuXino-LIME and A10-OLinuXino-LIME. The major differences between A20-OLinuXino-LIME2 and A20-OLinuXino-LIME are:

• LIME2 has gigabit Ethernet (GbE), compared to the standard 100Mb Ethernet of the LIME
• LIME2 design provides double the RAM memory, compared to the LIME design (1024 vs 512)
• Much better routing of DDR3 memory.
• Increased the number of layers from 6 in LIME to 8 in LIME2
• Corrected pinout of the LCD and GPIO connectors (shields designed for the LIME layout are not compatible with the LIME2 layout)

The A10 and the A20 processors are pin-to-pin compatible. Because of the processor, software-wise the board is closer to A20-OLinuXino-LIME than to the A10-OLinuXino-LIME. This resemblance to other designs definitely might speed the development on the board - a lot of software written for A20-OLinuXino-LIME might work out-of-the-box with A20-OLinuXino-LIME2. Additionally, pinout tables, GPIO maps, etc released for A20-OLinuXino-LIME would apply to A20-OLinuXino-LIME2 (except for the 0.05” step connectors - LCD display and all the GPIOs connectors, which have a different layout compared to both A20-OLinuXino-LIME and A10-OLinuXino-LIME).

uPico is a RP2040 powered expansion card designed to enhance the capabilities of Clockwork’s uConsole. uPico is fully compatible with RaspberryPi Pico, including LED pin(GPIO25).

All sources are open, including:

• PCB design
• Control application code
• Cover bracket 3D model

For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).

You’ll note there’s no I2S peripheral, or SDIO, or camera, what’s up with that? Well instead of having specific hardware support for serial-data-like peripherals like these, the RP2040 comes with the PIO state machine system which is a unique and powerful way to create custom hardware logic and data processing blocks that run on their own without taking up a CPU. For example, NeoPixels - often we bitbang the timing-specific protocol for these LEDs. For the RP2040, we instead use a PIO object that reads in the data buffer and clocks out the right bitstream with perfect accuracy. Same with I2S audio in or out, LED matrix displays, 8-bit or SPI based TFTs, even VGA! In MicroPython and CircuitPython you can create PIO control commands to script the peripheral and load it in at runtime. There are 2 PIO peripherals with 4 state machines each.

There is great C/C++ support, unofficial (but really good) Arduino support an official MicroPython port, and a CircuitPython port! We of course recommend CircuitPython because we think its the easiest way to get started and it has support with most our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.

While the RP2040 has lots of onboard RAM (264KB), it does not have built in FLASH memory. Instead that is provided by the external QSPI flash chip. On this board there is 2MB, which is shared between the program its running and any file storage used by MicroPython or CircuitPython. When using C/C++ you get the whole flash memory, if using Python you will have about 1 MB remaining for code, files, images, fonts, etc.

RP2040 Chip features:

• Dual ARM Cortex-M0+ @ 133MHz
• 264kB on-chip SRAM in six independent banks
• Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus
• DMA controller
• Fully-connected AHB crossbar
• Interpolator and integer divider peripherals
• On-chip programmable LDO to generate core voltage
• 2 on-chip PLLs to generate USB and core clocks
• 30 GPIO pins, 4 of which can be used as analog inputs
• Peripherals
• 2 UARTs
• 2 SPI controllers
• 2 I2C controllers
• 16 PWM channels
• USB 1.1 controller and PHY, with host and device support

TinyBLING doesn’t have an included ESP32-S3 + peripherals on the back, but instead provides headers to plug in an Unexpected Maker Tiny board (TinyPICO, TinyS2, TinyS3 and the new TinyC6) to act as the brains for your project.

You also get a STEMMA/QT connector and a bunch of IO and power broken out on an extra header, for easy expansion. TinyBLING still has a user programable power switch to enable or disable the power to the LED matrix (more on that below), plus 4 user programmable buttons.

Finally, hello SoloBLING!

SoloBLING is just the 40x8 RGB LED matrix on its own. It provides the BLING, you provide everything else.

The Raspberry Pi 5 is the newest Raspberry Pi computer, and the Pi Foundation knows you can always make a good thing better! And what could make the Pi 5 better than the 4? How about a faster processor, USB 3.0 ports, and an updated Gigabit Ethernet chip with PoE capability? Good guess - that’s exactly what they did!

The Raspberry Pi 5 is the latest product in the Raspberry Pi range, boasting 64-bit quad-core Arm Cortex-A76 processor running at 2.4GHz with built-in metal heatsink, USB 3 ports, dual-band 2.4GHz and 5GHz wireless LAN, faster Gigabit Ethernet, and PoE capability via a separate PoE HAT.

This version comes with 4 GB of RAM, but there’s also an 8GB version if you like.

Featuring a 64-bit quad-core Arm Cortex-A76 processor running at 2.4GHz, Raspberry Pi 5 delivers a 2–3× increase in CPU performance relative to Raspberry Pi 4. Alongside a substantial uplift in graphics performance from an 800MHz VideoCore VII GPU; dual 4Kp60 display output over HDMI; and state-of-the-art camera support from a rearchitected Raspberry Pi Image Signal Processor, it provides a smooth desktop experience for consumers, and opens the door to new applications for industrial customers.

For the first time, this is a full-size Raspberry Pi computer using silicon built in-house at Raspberry Pi. The RP1 “southbridge” provides the bulk of the I/O capabilities for Raspberry Pi 5 and delivers a step change in peripheral performance and functionality. Aggregate USB bandwidth is more than doubled, yielding faster transfer speeds to external UAS drives and other high-speed peripherals; the dedicated two-lane 1Gbps MIPI camera and display interfaces present on earlier models have been replaced by a pair of four-lane 1.5Gbps MIPI transceivers, tripling total bandwidth, and supporting any combination of up to two cameras or displays; peak SD card performance is doubled, through support for the SDR104 high-speed mode; and for the first time. the platform exposes a single-lane PCI Express 2.0 interface, providing support for high-bandwidth peripherals.

The ESP32-C6-DevKitC-1-N4 is an entry-level development board equipped with ESP32-C6-WROOM-1, a general-purpose Wi-Fi + Bluetooth LE RISC-V MCU module that integrates complete Wi-Fi and Bluetooth LE functions. This board integrates complete Wi-Fi, Bluetooth LE, Zigbee, and Thread functions.

This version is equipped with the ESP32-C6-WROOM-1 with 4MB Flash.

Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-C6-DevKitC-1-N8 on a breadboard. We particularly like that there’s a debug UART/USB port and a separate native USB port, so you can upload/debug/USB all at once.

At the core of the modules is an ESP32-C6, a RISC-V 32-bit single-core CPU that operates at up to 160 MHz. You can power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for changes or crossing of thresholds. ESP32-C6 integrates a rich set of peripherals including SPI, LCD, Camera interface, UART, I2C, I2S, remote control, pulse counter, LED PWM, USB Serial/JTAG controller, MCPWM, SDIO host, GDMA, TWAI? controller (compatible with ISO 11898-1), ADC, touch sensor, temperature sensor, timers, and watchdogs, as well as up to 45 GPIOs. It also includes a full-speed USB 1.1 On-The-Go (OTG) interface to enable USB communication

There are three mutually exclusive ways to provide power to the board:

• USB Type-C to UART Port, default power supply
• 5V and GND pin headers
• 3V3 and GND pin headers

It is recommended to use the first option: USB Type-C to UART Port.

Components:

• ESP32-C6-WROOM-1: ESP32-C6-WROOM-1 is a general-purpose module supporting Wi-Fi 6, Bluetooth 5, and IEEE 802.15.4 (Zigbee 3.0 and Thread). This module is built around the ESP32-C6 chip, and comes with a PCB antenna and 4 MB SPI flash.

Make memories, or just a cool camera-based project, with Adafruit’s MEMENTO Camera Board. It’s a development board with everything you need to create programmable camera and vision projects: with a camera module, TFT preview screen, buttons, SD card slot and driven by a powerful ESP32-S3 with 2 MB of PSRAM for buffering 5 MegaPixel camera images.

This product is just the mainboard, and does not come with an enclosure, LED ring, hardware, SD card, or battery.

The ESP32-S3 is a WiFi and Bluetooth LE capable, 240 MHz dual core Tensilica processor - much like the famous ESP32. The S3 adds native USB support so it’s great for use with Arduino or CircuitPython. The S3 also has the ability to interface with raw camera modules. The cameras require 12 GPIO pins and fast data transfer in order to get images off the sensor, and then a lot of memory for storing 2560 x 1920 images - which is why we picked an S3 module with 2MB of PSRAM so that we can read JPEGs into memory for saving onto an SD card.

To make the board easy to use we added a ton of supporting hardware, here’s a full list of the hardware included:

• ESP32-S3 module with 8 MB Flash, 2 MB PSRAM - dual core 240MHz Tensilica with WiFi and BTLE.
• OV5640 camera module with 72 degree view and auto-focus motor - 5MP camera sensor with JPEG encoder built in.
• 1.54” 240x240 Color TFT - For previewing the camera images, or user interface design.
• MicroSD card slot - Store images or animations to any SPI-capable micro SD card.
• Two Digital/Analog Stemma Ports - JST PH-3 connectors for A0, A1 and power+ground for adding external buttons, LEDs, or sensors. Can provide 3V or 5V power.
• I2C Stemma QT Port - Connect just about any I2C sensor you please with a Stemma QT JST SH port, provides 3.3V power and logic.
• LIS3DH Accelerometer - Triple-access accelerometer can detect orientation, shaking or movement.
• LiPoly battery charging support - Use a 3.7/4.2V 350mA or 420mA battery for on-the-go snaps.
• 6 User Buttons - change modes, preview saved images, play DOOM (?). Connected through a GPIO expander
• Buzzer - play tones or alerts, or indicate when a photo was successfully taken
• Analog Microphone - Can be used as a sensor to detect loud sounds, not for recording video with audio.
• Shutter button - Connected to GPIO 0 for entering the ROM bootloader
• Reset button - For entering the bootloader or starting over
• On/Off switch - Cut all power when using a battery
• USB Type C for programming the ESP32-S3, as well as REPL access in CircuitPython and charging the optional LiPoly battery
• Breakout pads for hardware UART - for more intense debugging needs, solder wires to the through-hole pads to connect to a console cable.
• Four M3 standoffs for mounting or enclosure attachment.

We’ve got both Arduino and CircuitPython example code that lets you preview the camera, adjust settings, and take photos that are saved to disk. However, we recommend CircuitPython because the compilation time in Arduino is pretty intense due to the huge amount of code required to run the camera. CircuitPython is fast to develop for and our library will make it easy to start making custom camera projects.

Tiny, but mighty! This board with a powerful ESP32-S3 MCU measures in at 24.8mmx18mm (23.5mm for just the PCB, the USB-C connector sticks out a little bit). Despite it’s small size it still exposes a wealth of GPIO connections - a whopping 34 in total. It does however have ‘only’ 4MB of Flash storage rather than the more typical 8MB found on most ESP32-S3 boards (and even 16MB on some).

• ESP32-S3FH4R2 dual-core Xtensa? 32-bit LX7 processor - up to 240MHz
• USB Type-C Port
• ME6217C33M5G low dropout LDO, 800mA (Max)
• WS2812 RGB LED
• BOOT button Press it and then press the RESET button to enter download mode
• RESET button
• 34 GPIO contacts (18 available on breadboard friendly castelated edges, 16 on the bottom of the board through exposed pads)
• 2.4G ceramic antenna
  • Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth? 5 (LE) although CircuitPython at the time of writing does not offer proper Bluetooth supports for ESP32-S3 chips, a NRF52840 based board will serve you better in that regard
• Built in 512KB of SRAM and 384KB ROM, onboard 4MB Flash memory and 2MB PSRAM
• Castellated module and onboard ceramic antenna, allows soldering direct to carrier boards
• Supports flexible clock, module power supply independent setting, and other controls to realize low power consumption in different scenarios
• Integrated with USB serial port full-speed controller, 34 × GPIO pins allows flexibly configuring pin functions
  • 4 × SPI, 2 × I2C, 3 × UART, 2 × I2S, 2 × ADC, etc.

Due to the limited flash memory available on this board it hasn’t been ‘build’ with esp-camera support - if that’s something you want to use you’ll have to roll your own build and sacrifice some other feature to make space (like the at the moment non-functional bluetooth)

There’s a few things everyone loves: ice cream, kittens, and honkin’ large TFT screens. We’re no strangers to small TFT’s - from our itsy 1.14” color display that graces many-a-TFT-Feather to our fancy 3.5” 320x480 breakout screen. But most people who dabble or engineer with microcontrollers know that you sort of ‘top out’ at 320x480 - that’s the largest resolution you can use with every day SPI or 8-bit 8080 interfaces. After that, you’re in TTL-interface TFT land, where displays no longer have an internal memory buffer and instead the controller has to continuously write scanline data over a 16 or 18 or 24 pin interface.

RGB TTL interface TFT displays can get big: they start out at around 4.3” diagonal 480x272, and can get to 800x480, 800x600 or even 720x720. For displays that big, you need a lot of video RAM (800x480 at 24 bit color is just over 1MB), plenty of spare GPIO to dedicate, and a peripheral that will DMA the video RAM out to the display continuously. This is a setup familiar to people working with hefty microcontrollers or microcomputers, the sort of device that run cell phones, or your car’s GPS navigation screen. But until now, nearly impossible to use on low cost microcontrollers.

The ESP32-S3 is the first low-cost microcontroller that has a built in peripheral that can drive TTL displays, and can come with enough PSRAM to buffer those large images. For example, on the Adafruit Qualia ESP32-S3 for TTL RGB-666 Displays, we use a S3 module with 16 MB of Flash and 8 MB of octal PSRAM. Using the built in RGB display peripheral you can display graphics, images, animations or even video (cinepak, natch!) with near-instantaneous updates since the whole screen gets updated every ~30FPS.

This dev board is designed to make it easy for you to explore displays that use the “secondary standard’ 40-pin RGB-666 connector. This pin order is most commonly seen on square, round and bar displays. You’ll want to compare the display you’re using to this datasheet, if it matches you’ll probably be good! One nice thing about this connector ordering is that it also includes pins for capacitive touch overlay, and we wire those up to the ESP32-S3’s I2C port so you can also have touch control with your display.

Don’t forget! This is just the development board, a display is not included. Use any RGB-666 pinout display with or without a touch overlay. Note that you will need to program in the driver initialization code, dimensions, and pulse widths in your programming language. Here are some known-working displays that you can use in Arduino or CircuitPython:

• 2.1” 480x480 Round with Capacitive Touch
• 2.1” 480x480 Round without touch
• 4” 720x720 Square with Capacitive Touch
• 4” 720x720 Round without touch
• 4.6” 960x320 Rectangular Bar

On the Qualia board we have the S3 modules, with 16 pins connected to the TFT for 5-6-5 RGB color, plus HSync, VSync, Data Enable and Pixel Clock. There’s a constant current backlight control circuit using the TPS61169 which can get up to 30V forward voltage and can be configured for 25mA-200mA in 25mA increments (default is 25mA). Power and programming is provided over a USB C connector, wired to the S3’s native USB port. For debugging, the hardware UART TX pin is available as well.

Since almost every GPIO is used, and almost all RGB-666 displays need to be initialized over SPI, we put a PCA9554 I/O expander on the shared I2C bus. Arduino or CircuitPython can be instructed on how to use the expander to reset and init the display you have if necessary. The remaining expander pins are connected to two right-angle buttons, and the display backlight.

The expander is what lets us have a full 4-pin SPI port and two more analog GPIO pins - enough to wire up an MMC in 1-wire SDIO mode along with an I2S amplifier to make an A/V playback demo. Maybe we can even eat ice cream while watching kitten vids! There is also the shared I2C port, we provide a Stemma QT / Qwiic port for easy addition of any sensor or device you like.

LeMaker Banana Pro is an updated version of its predecessor Banana Pi, a low-cost single-board computer.

The Banana Pro is a credit card-sized and low-power single-board computer developed in China by the LeMaker Team, with the goal of promoting STEM (science, technology, engineering and mathematics) education in schools.

Like its smaller sibling the Banana Pi, the Pro concept is heavily influenced by the Raspberry Pi, however the Banana Pro provides various enhancements over prior designs.

The Banana Pro has an Allwinner A20 system on a chip (SoC), which includes an ARM Cortex-A7 Dual-core (ARMv7-A) 1 GHz, Mali-400 MP2 GPU and 1GB DDR3 SDRAM.

The Banana Pro uses a microSD card for booting an OS, but also includes a SATA 2.0 interface to allow connection of a hard disk for additional storage, however you cannot boot from the hard disk.

Other differences from the Banana Pi include on-board Wi-Fi 802.11b/g/n AP6181, integrated composite video and audio output into a 3.5 mm TRRS jack. This makes space for a 40-pin extension header.

A wild Kee Boar appears! It’s a shiny KB2040! An Arduino Pro Micro-shaped board for Keebs with RP2040. (#keeblife 4 evah) A lot of folks like using Adafruit parts for their Keeb builds – but with the ItsyBitsy not being pin-compatible with the Pro Micro pinout, it really wasn’t very easy without some sort of adapter plate.

Now we’re seeing lots of people use CircuitPython for keebs, which is awesome! So why not try our hands at spinning up a pro-micro-compatible RP2040 board? The RP2040 is plenty powerful, low-cost, and makes for an excellent keeb driver chip.

We mixed together what we liked most about the SparkFun Pro Micro RP2040 (Qwiic / STEMMA QT I2C port on the end, so good!) and Elite-C (castellated pads & pins for D+ and D-) and our existing RP2040 boards (boot button can be used for user, 8MB QSPI flash, onboard NeoPixel, jumper for skipping the diode/fuse for high power RGB LEDs or USB hosting). We even got it to all fit on a 2-layer PCB with 7/7 routing – just needed to make the smallest caps and resistors 0402.

With 20 GPIO available (18 on castellated pins, 2 on STEMMA QT port) you can easily make up to 100-keys matrices, or common 65% 5x15 layouts. Use a plug-and-play QT cable to connect to the last two pins without having to do any desoldering/rework.

Technical details

• Same size and form-factor as a Pro Micro breakout and nearly-identical pinout (this board has fewer analog pins, for example)
• Measures 1.3” x 0.7” without headers soldered in
• RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3 V logic and power. 264 KB RAM, No EEPROM. 12 MHz crystal for perfect timing.
• 8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code storage.
• 20 GPIO pins with following capabilities:
  • 18 GPIO on castellated/pin breakout pads. 2 GPIO on QT port that can be easily accessed for 5x15 keyboard layouts.
  • 4 12 bit ADCs
  • 2 I2C, 2 SPI and 2 UART peripherals, we label one of for the ‘main’ interface in standard Pro Micro locations
  • 16 PWM outputs - for servos, LEDs, etc
  • The 10 digital non-ADC GPIO are consecutive for maximum PIO compatibility
• RGB NeoPixel for colorful status indiction
• Classic green power LED
• Both Reset button and Bootloader select button for quick restarts. Bootloader button is also available as a generic GPIO input button.
• STEMMA QT connector on the end is compatible with the SparkFun Qwiic I2C connector, and can be used to plug and play I2C devices, or just as 2 extra GPIO pins.
• 3.3 V regulator with 500 mA peak current output
• RAW output, for powering NeoPixels or other 5 V devices. Jumper on bottom lets you skip over the 500 mA fuse, for up to 2 A from USB ports.
• USB-C connector lets you access built-in ROM USB bootloader and serial port debugging
• Extra D- and D+ breakouts for alternative USB connection options.

• Access to 23 GPIO pins to use on your keyboard, meaning that on any Aurora Series keyboard, you’ll have 5 pins left over for any modifications you may want to do.
• Rear-facing bootloader button allowing you to easily recover from a bricked firmware, even when mounted in the usual upside-down position.
• An ultra-low profile with a mid-mounted USB-C port and a mere 1mm thick PCB. The rear-mounted reset button checks in at only 0.35mm, too, like it’s almost not there.
• Supports at least 1A of power output, so you can maximize the output of your LEDs when your computer outputs enough power.

Advanced features

The default settings are right for most people out of the gate. For those who demand more of their controller, we have some advanced features:

• 5V tolerant I2C pins so you won’t have to worry when hooking up an I2C device like an OLED or trackball board;
• Runs at 3.6V for better 5V signal compatibility so your LEDs will listen better to those smooth colour change commands (according to data sheets, 3.5V is the minimum to reliably talk with LEDs);
• Selectable voltage on the VCC (defaults to 5V to support RGB LEDs) and RAW pins (which we named VA, and isn’t connected by default to be compatible with common Corne-style kits that bridge VCC with RAW on the keyboard by default) for when you need to get specific with your kit;
• USB data pads for hand wired builds where you want to have a separate USB port somewhere else on the board;
• Debug pads to be able to better look into microcontroller behaviour when you really need to.

The PicoADK is a RP2040 based Audio Development Kit, which allows you to build your own digital oscillators, synthesizers, noise boxes and experiment around. It has all the base features of the Raspberry Pico / RP2040, plus a high quality Audio Output, 8 Analog Inputs for connecting potentiometers, control voltage from Eurorack systems or even additional input signals.

Why did you make it?

I made it initially for myself to build digital oscillators for a hybrid synth and to experiment with the RP2040 as a DSP.

What makes it special?

It has a 32-bit Audio Codec and an SPI 8x 12-bit ADC and is only longer by 4 pins on each side than the Raspberry Pico!

Specifications

• RP2040 Dual Core 133MHz Cortex M0+ (running at 2x 400MHz Overclocked in the RTOS Template)
• 2MB Flash (plenty for synthesizers and sound generators)
• Very low noise LDO regulators (separate LDO for digital circuits and separate for analog circuits)

Choo! Choo! This is the RP2040 Metro Line, making all station stops at “Dual Cortex M0+ mountain”, “264K RAM round-about” and “16 Megabytes of Flash town”. This train is piled high with hardware that complements the Raspberry Pi RP2040 chip to make it an excellent development board for projects that want Arduino-shape-compatibility or just need the extra space and debugging ports.

• RP2040 main chip, 133MHz clock, 3.3V logic
• 16 MB of QSPI flash for program storage
• 24 GPIO, 4 of which are also analog inputs
• Micro SD card socket wired up for SPI interfacing, also has extra pins connected for advanced-user SDIO interfacing (note that there’s no released usage code for SDIO in Arduino/Python, so this is a super-cutting-edge setup)
• Onboard RGB NeoPixel
• Onboard #13 LED
• Stemma QT port for I2C peripherals and sensors
• Reset and Boot buttons on PCB edge
• Pico Probe debug port - 3 pin JST SH compatible
• SWD debug port - 2x5 0.05” standard connector
• USB Type C power and data
• 5.5mm / 2.1mm DC jack for 6-12VDC power
• On/off switch for DC jack
• GPIO pin numbers match classic Arduino pins, other than A4/A5 which are D24 and D25 (there’s only 4 ADC pins on the RP2040)
• RX / TX switch for swapping D0 and D1 locations

You may be wondering about the RX-TX switch: we added this because traditional Arduino board start counting the GPIO for the digital pins with 0-7 and then 8-13. However, the D0/D1 pins are also traditionally the hardware UART Serial1, where D0 is Rx and D1 is Tx. On the RP2040, however, the UART pins are the other around: D0 is Tx and D1 is Rx. Thus a DPDT switch: flip one way to have the GPIO go in order of 0-7, flip the other way to have the logical locations of the hardware UART correct but now the pin order is 1, 0, 2, 3..7. Of course, it’s also handy if, like us, you often swap the pins - now you don’t need to require or cut/solder traces!

About the RP2040

The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit or DSP hardware support - so if you’re doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you’ll get close-to-M4 speeds!

For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).

You’ll note there’s no I2S peripheral, or SDIO, or camera, what’s up with that? Well, instead of having specific hardware support for serial-data-like peripherals like these, the RP2040 comes with the PIO state machine system, which is a unique and powerful way to create custom hardware logic and data processing blocks that run on their own without taking up a CPU. For example, NeoPixels - often we bitbang the timing-specific protocol for these LEDs. For the RP2040, we instead use PIO object that reads in the data buffer and clocks out the right bitstream with perfect accuracy. Same with I2S audio in or out, LED matrix displays, 8-bit or SPI based TFTs, even VGA! In MicroPython and CircuitPython, you can create PIO control commands to script the peripheral and load it in at runtime. There are 2 PIO peripherals with 4 state machines each.

There is great C/C++ support, unofficial (but really good) Arduino support, an official MicroPython port, and a CircuitPython port! We, of course, recommend CircuitPython because we think it’s the easiest way to get started, and it has support with most of our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.

While the RP2040 has lots of onboard RAM (264KB), it does not have built-in FLASH memory. Instead, that is provided by the external QSPI flash chip. On this board, there is 16 MB, which is shared between the program it’s running and any file storage used by MicroPython or CircuitPython. When using C/C++, you get the whole flash memory, if using Python, you will have about 15 MB remaining for code, files, images, fonts, etc.

RP2040 Chip features:

• Dual ARM Cortex-M0+ @ 133MHz
• 264kB on-chip SRAM in six independent banks
• Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus

• JTAG 2x5 Header for more intense debugging
• Serial debug output pins (optional, for checking the hardware serial debug console)
• STEMMA QT connector for I2C devices, with switchable power, so you can go into low power mode.
• On/Charge/User LEDs + status NeoPixel with pin-controlled power for low power usage
• Low Power friendly! In deep sleep mode we can get down to ~100uA of current draw from the Lipoly connection. Quiescent current is from the power regulator, ESP32-S3 chip, and Lipoly monitor. Turn off the NeoPixel and external I2C power for the lowest quiescent current draw.
• Works with ESP-IDF, Arduino or CircuitPython

Folks love our wide selection of RGB matrices and accessories for making custom colorful LED displays… and our RGB Matrix Shields and FeatherWings can be quickly soldered together to make the wiring much easier. But what if we made it even easier than that? Like, no solder, no wiring, just instant plug-and-play? Dream no more - with the Adafruit Matrix Portal S3 add-on for RGB Matrices, there’s never been an easier way to create powerful Internet-connected LED displays.

You can plug directly into the back of any HUB-75 compatible display (all the ones we stock will work) from 16x32 up to 64x64 or use the stock 2x8 IDC cables to plug into the front. Use the included screws to attach the power cable to the power plugs with a common screwdriver, then power it with any USB C power supply. Chain dozens of displays for long stretches, or you can panelize them in a grid for bigger displays. For larger projects, power the matrices with a separate 5V power adapter.

Then code up your project in CircuitPython or Arduino, our Protomatter matrix library works great on the ESP32-S3 chipset, knowing that you’ve got the wiring and level shifting all handled. Here’s what you get:

• ESP32-S3 processor, 8 MB flash, 2 MB of SRAM, with full Arduino or CircuitPython support
• WiFi and Bluetooth LE baked right in, full Arduino support. CircuitPython only supports WiFi at this time, not BLE on the S3 chip.
• USB Type C connector for data and power connectivity
• I2C STEMMA QT connector for plug-n-play use of any of our STEMMA QT devices or sensors can also be used with any Grove I2C devices using this adapter cable
• JST 3-pin connector that also has analog input for quick connection with any JST PH 2.0mm pitch cable.
• LIS3DH accelerometer for digital sand projects or detecting taps/orientation.
• GPIO breakout strip - has reset, boot selection, TX debug output, and 6 GPIO including 4 analog inputs with PWM, SPI, or I2S support for adding other hardware.
• Address E line jumper for use with 64x64 matrices (check your matrix to see which pin is used for address E, we default to pin 8
• Two user interface buttons + one reset button
• Indicator NeoPixel and red LED
• Green power indicator LEDs for both 3V and 5V power
• 2x10 socket connector fits snugly into 2x8 HUB75 ports without worrying about ‘off by one’ errors
• 2x8 IDC plug connector works with standard cables that come with matrices.

The Matrix Portal uses an Espressif ESP32-S3 Wi-Fi+BLE chipset, and has dropped the SAMD51 from the original Matrix Portal due to silicon shortages. But turns out the S3 is really great at doing all the work of the original all on its own:

• The S3 has a parallel output drive peripheral which means that controlling the matrix is done without bitbanging.
• The S3 has two cores so one can be dedicated to WiFi networking or matrix control while the other runs your code.
• With native USB, its easy to have it act like a keyboard, or mouse, or MIDI device and it also has plenty of I2C, SPI, I2S, UART and analog inputs.
• Lots of memory: 8MB of Flash means plenty of space for code, files, GIFs and more. 2MB of PSRAM means you can read and parse a lot of IoT data and still have plenty of RAM for the matrix display buffers.
• The only real thing missing from the original Matrix Portal is the S3 does not have an analog output DAC pin, we recommend an I2S amplifier for audio instead.

Comes with one fully programmed and assembled MatrixPortal, preprogrammed with a basic display demo for 32x64 LED matrices.

You can use the built-in RTC (BM8563) to keep track of time to create custom, specific sleep and wake-up schedules. In deep sleep, the standby current of the entire Camera X can be as low as 10 μA. This camera supports sending images through WiFi and via the USB serial debug port. The bottom HY2.0-4P I2C port output can be connected to other I2C peripherals such as Grove or Stemma QT devices when this cable is in use.

A friendly heads-up: The low-power power management used by the Timer Camera series is different from the CORE and StickC devices. When in use, the PWR button is used as a power-on button (long press 2 seconds). If you need to shut down the device, use the software API or press the Reset button on the PCB.

Note: as 2025-08-06 there is no documented way to use the camera. Examples using espcamera produce initialization errors.
