Description

Firmware at https://github.com/wahtak/whtkbrd 

 

Schematic and layout based on https://github.com/TeXitoi/keyseebee

 

Part numbers included for fabrication by JLCPCB (without switches)

 

Errata -- Fix before fabrication

- TX and RX needs to be swapped on one side

- Missing pin pulled to GND to indicate side, can be done connecting SCL to GND
