I started with picking up Raspberry Pico as out main microcontroller and this would be a 60 % layout Keyboard with 2 rotor encoders. The rotor encoders will be use to control Brightness and Volume and the switch in those 2 encoders will act as a custom key to take screenshot and to delete. I also did the schematic of the keyboard, I added the stabilizers to the switches which were longer then 1.75U. The Keyboard uses a matrix grid so i need only a few gpio pins for the whole keyboard to work.rk.
- Base on Raspberry pico
- Has 61 keys ( 60% Keyboard Matrix)
- Has 2 Rotor Encoder
