From the project

Three key USB media hackpad with XIAO RP2040, KMK firmware, and 3D printed case

This is a small USB macropad for quick media controls. It uses three MX-style switches with a Seeed Studio XIAO RP2040 mounted on the back of the PCB. The case is a two-part 3D printed sandwich design with a bottom tray and a top switch plate.

The firmware is written with KMK. The default keymap is:

- CAD/ has the full case model and OpenSCAD source. - PCB/ has the KiCad project files. - Firmware/ has the original KMK firmware source. - production/ has the gerbers, printable case files, and firmware file.
