From the project

A 6-key macropad with a rotary encoder, built for the Hack Club Hackpad program.

A 6-key macropad with a rotary encoder, built for the Hack Club Hackpad program.

Single-piece, fully 3D printed case (CAD/hackpadassembly.step`).

Runs KMK on the Seeeduino XIAO. Keys are direct-wired to GPIO pins (no diode matrix). See Firmware/main.py for the pin mapping (extracted from the schematic) and keymap.

1. Order the PCB using production/gerbers.zip 2. 3D print / laser cut the case from CAD/ 3. Flash Firmware/main.py to the XIAO via KMK/CircuitPython 4. Assemble and solder switches per the BOM above
