3x3 Macropad aiming to recycle Switch Testers
This repository contains all required files to build a Recycling Pad
which is a plugin extension for the Keygem Switch Tester.
It features 3x3 keys, whereby any of the upper three once can be replaced by EC11 encoder(s).
Depending on your setup, you can replace any number of the upper switches with EC11 rotary encoders.
As the whole PCB is quite tight packed, you need to keep an eye on the soldering order. If you use Millmax Sockets, it's getting easier as you can remove the switches if required.
Depending on the length of your Headers, you might want to cut them after soldering. Otherwise they might touch the PCB and shortcircuit a switch.
The qmk
folder contains some base configurations for the Pad.
Note: rows and columns are switched, therefor your configuration needs to be rotated 90° (see example configs).
