This is a devboard powered by the RP2040 chip! It features 40 pins broken out (20 per side) for easy prototyping and a plus‑sign of 5 RGB LEDs to animate whatever your heart desires.
I built this project as a way to learn full PCB design, from schematics to routing to firmware. It’s also a great way for others to prototype their own ideas, with colorful lighting built in to make experimentation more fun and expressive.
- Power the board with USB-C
- To use MicroPython, hold the button (the board will appear as a USB drive named RPI-RP2) and flash the MicroPython UF2 firmware with the MicroPython RP2040 Documentation.
- Once MicroPython is installed, copy your Python files to the board.
- Then, experiment! Use the 40 broken‑out pins (GPIO, power, and ground) to connect sensors, modules, or breadboards. Check out the firmware in the /firmware folder in this repository for an example of how to control the on-board LEDs. Enjoy!
Here is the schematic:
And here is the finished PCB in the editor:
This is what the final devboard will look like:
