Simple handwired 3x3 mechanical keyboard macropad. Can easily be flashed with QMK / VIAL for customization. The screws are hidden at the bottom of the case.
I recommend watching Joe Scotto's youtube guide for handwiring and configuring with QMK/VIAL. The only difference is the micro controller, I used the "Pin map" section of https://wiki.seeedstudio.com/XIAO-RP2040/ as reference, the pin names are the "GPIOXX" section.
I printed the case and plate with Prusament Galaxy Black PLA, 0.2mm Layer height and 0.4mm Nozzle on a Prusa Mini+.
