This is a 6-key macropad arranged in a 2x3 matrix, with a rotary encoder for analog-style control and a 0.91” OLED for live feedback. It is built on a custom PCB, with the Seeeduino XIAO RP2040 socketed on top. It runs QMK, so every key, layer, and encoder action is fully remappable, and you get access to the entire QMK feature set (layers, tap-dance, macros, combos.The whole thing is housed in a 3D printed case designed to hold the PCB, switches, encoder, OLED, and XIAO board in place.
