KMK Open Source Mechanical Keyboard Firmware Written in CircuitPython

This video is sponsored by PCBWay. Only $5 for 10 PCBs and Only $4.98 for 3D Printing + Express 24 hour service on http://www.pcbway.com/ KMK is an open source firmware for mechanical keyboards. It is written in CircuitPython, a derivative of Python for constrained embedded devices. KMK and CircuitPython run on various microcontrollers, including RP2040. In this video KMK is demonstrated using a printed circuit board with Seeed XIAO RP2040 module. The video shows hot-swap mechanical switches, backlight, RGB underflow with Neopixes, mini I2C OLED display and a rotary encoder.
