A compact 6-key macropad with a rotary encoder and OLED display, built around the Seeeduino XIAO RP2040 and running QMK firmware. Small footprint, fully custom, and 3D printed.

Reads raw muscle electrical signals (EMG) from a forearm electrode cuff, processes them through a 4-stage analog signal chain, classifies the gesture using a random forest running on the ESP itself.
