From the project

PMK - Full wireless split keyboard

The goal is to make a suit of wireless devices such as "smart keyboard" (combined mouse and keyboard), gamepad, LEDs, knobs, display, etc The first step is to make a wireless split keyboard, and then we will see later...

Currently, you can connect up to 8 (software limited) devices per dongle, each of them having up to 8 (software limited) layers. Layers only affect keyboards and LED.
