From the project

A simple, open-source 9-key macro pad with QMK firmware and 3D-printable case

A simple, open-source 9-key macro pad powered by Seeeduino XIAO RP2040.

This is an example of a fully built case with the a simple green rectangle to show the pcb

It is a simple case disigned for a 9 keys in a 3by3 format close to eachother

I am pretty proud of this design and I learned to use tags to stop it from getting messy :)

My PCB is a little unproffesional but I learned to use Vias to stop my wiring to go all over the place.
