Description

3D printed Macropad with 12 MX-switch keys (4x3 + 2) and 2 EC11 rotary encoders which can run both KMK and QMK firmwares. 

PCB design is freely available here at my GitHub profile.

The PCB design was done in order to create a cost effective and minimal requested components macropad, therefore only necessary components were put on the PCB.

Hi guys, I'm an engineering student and in my spare time I like to work on custom PCBs. More and more different sizes macropads are coming, still all strictly open source. Boost the model, if you want and if you enjoy my creations.
