5x5 aka Gojira!
This is my first custom keyboard, a 5x5 cherry mx matrix based on the STM32F1 with libopencm3. The project contains firmware, schematics and a board layout in kicad.
This project is intended as a platform for custom keyboard development. It supports:
- usb keyboard scancodes
- bios boot and nkro
- system / consumer codes
- generation of mouse events
- usb serial interface
The board is programmed using a 6-pin TagConnect, that must be wired to a STM Discovery SWD/STLink programming port. Note that the PCB includes footprints for firewire connectors for future i2c experiments. The current firmware has no code for this yet.
