5*5cm control pad with an encoder, runs QMK firmware.
This is a POC project to prove my PCB design works, especially the encoder (knob) part. On the other hand, I want to practise my soldering skills before I could create some serious stuff. The next try would be making a mechanical keyboard that totally applies my personal preference, without a breakout board (bye bye Pro Micro).
