How to use it / Build it
Firsly,printing all 3d models after that fabricate PCB.After that assemble mx switches,MCU and battery management of pcb.then assemble all this parts together.finally,upload firmware on nice nano and pico,the test all
Schematic
I made the schematic and keyboard matrix for the corne keyboard, then the numpad .
