#Baumkuchen

Baumkuchen is a 13-key macropad with a radial key layout.
The board can be used as a circuit or as a switch plate by cutting out the keyswitch Pro Micro part.
It is compatible with Cherry MX compatible keyswitches, and a rotary encoder can be optionally installed.
LEDs can also be mounted to make it glow.
The board is reversible, allowing you to choose the arrangement of keys and Pro Micro according to your usage style.
