This new guide by John Park shows you how to build your own custom mechanical keyboard that runs CircuitPython on the RaspberryPi Pico RP2040!
With lots of pins, the RaspberryPi RP2040 Pico makes for a great brain of a mechanical keyboard/macro pad — no scan matrix required. Up to 26 keys can be used with direct GPIO pins. You’ll learn how to make your own PCB design in Fritzing to send off for fabrication. A 3D printed or laser cut case finishes it off in style.
