POWER-UP PCBA #19: Speed up TinyML development with Seeed XIAO RP2040 and FREE Prototypes with Seeed Fusion
What can ignite your desire to be creative in an instant?
Earlier this year, Seeed introduced the XIAO RP2040 to the XIAO family. With XIAO RP2040, you get the same powerful microcontroller as the Raspberry Pico, but with the popular production-ready XIAO form factor.
XIAO RP2040 opens up more powerful XIAO applications with direct support for MicroPython and CircuitPython. To support and inspire more XIAO RP2040 projects, Seeed Fusion are offering 2 free PCBA prototypes with the Seeed Fusion PCBA service. Don’t let this amazing opportunity pass you by.
How powerful is Seeed XIAO RP2040?
The XIAO RP2040 is equipped with the Raspberry RP2040 chip that features a powerful dual-core Arm Cortex-M0+ processor with a flexible clock running up to 133 MHz.
Onboard, there is also 264KB of SRAM and 2MB of on-board Flash memory, allowing you to store and run more complex programs. Despite the superior performance and processing power, this little board uses very little power. Moreover, an article on Electronics-Lab also introduce more features to Seeed XIAO RP2040, please click here to find out more.
Seeed XIAO RP2040 is built with rich interfaces in a tiny thumb size, and fully supports Arduino, MicroPython, and CircuitPython. The onboard interfaces are enough for developing multiple applications, ideal for various wearable, TinyML, rapid prototyping. It’s also perfect for all the projects needing a mini Arduino, custom mechanical keyboards, USB development (USB to multi-channel TTL/USB host mode, etc.) and small projects.
XIAO RP2040 is as small as the Seeeduino XIAO but more powerful and supports CircuitPython out of the box. Here is an interesting project by British developer, Andy Warburton who has been expatting in Amsterdam.
“I recently got into Mechanical Keyboard customization and thought it would be fun to build my own 8 key mechanical macropad. The process is pretty easy and made even easier with the addition of the Seeeduino Xiao which is super cheap and has enough inputs to create a decent sized keypad without the complexities of figuring out how to code a matrix (which if you feel like doing you could create a pad of up to 25 keys with this tiny device!). Let’s do this!“
The project has brought a good response to the community and received a lot of attention, hopefully it will give you a little bit of inspiration to customize your design with Seeed XIAO RP2040.

Case Study 1 – DIY 6-keys Macropad using Seeed XIAO RP2040 & Fusion PCBA
How interesting it would be if you DIY yourself a Macropad?
Naveen Kumar, who is a Senior Technical Scientist from Tokyo, had make a 6-keys Macropad by using Seeed Studio XIAO RP2040, which is a tiny development board.
And also, it was the first time for him to make PCB design project using KiCad EDA.
This project showcases a PCB design for a basic Macropad. Similar approaches can be applied to make a full-fledged advanced version of it.
Case Study 2 – 8-keys KEM Keyboard Extender Maker project using Seeeduino XIAO & PCBA
What an amazing project Jorge has done! The microprocessor that Jorge have used is a small Seeeduino XIAO SAMD21 Cortex M0+ development board that is perfect to be integrated into a PCB.
The rest of the basic components:
- 4x WS2812B RGB leds
- 8x WS2812 2020 RGB leds
- 8x transparent keys
- 8x MX Switches for PCB

Case Study 3 – 8-Keys Keyboard for Handwiring ‘Le Pinceau’ using Seeed XIAO BLE-nRF52840 & Fusion PCBA
“I’m using a XIAO BLE nRF52840 controller with ZMK firmware. The bluetooth is really convenient. 20 wpm and counting!” This is a project from the keyboard maker Caleb Goates and hopefully it will give you a little bit of inspiration to customize your design with Seeed XIAO RP2040.
Case Study 4 – Seeed Studio XIAO RP2040 18 Key Numpad
A minimalist 18 key numpad created by Scrapyard by using the Seeed Studio XIAO RP2040, a single analogue pin, and room for expansion!
Case Study 5 – Cistercian keyboard
Tauno Erik made this amazing Cistercian Keyboard, a keypad with cipher numerals based on an XIAO RP2040 and a custom Fusion PCB, which contains four columns and five rows of switches.
Case Study 6 – Slice36 Minimalist Split Keyboard
MReavley’s Slice36 is a minimalist ergo split keyboard, he designed the split to work over I2C, but was able to use the PIO feature of the RP2040 to reconfigure those pins to UART to work with KMK.
Case Study 7 – First Hummingbird of the season
A wireless Hummingbird by u/filibustercrankcase sporting a Seeed XIAO BLE controller.
Case Study 8 – Custom-programmable, mini keyboards with Seeed XIAO RP2040
ANAVI Knob 1 and ANAVI Knobs 3 are open source, custom-programmable, mini keyboards with Seeed XIAO RP2040 and rotary encoders. Both keyboards are powered by the open source firmware KMK written in CircuitPython. The printed circuit boards are designed with KiCad. An extra slot allows attaching I2C peripherals such as mini OLED displays.
We look forward to more enthusiasts joining us to make an interesting DIY Macropad/Keyboard project using XIAO RP2040 & Fusion PCB Assembly service for 100% FREE!!

I wrote a tutorial on using the XIAO RP2040 using Circuitpython. There is specific firmware for the card, but it is not available in the Adafruit downloads area. Contrary to what is reported on your Wiki, the card does not work properly using the firmware for Raspberry Pi Pico.
Can you link to the tutorial?
The admin bot does not allow me to share the link.
You can search the Seeed forum or my Github for my username djairjr.
