Tutte Coxeter 36k
This is firmware for a Raspberry Pi Pico PR2040 controller monoblock 36 key design (split 3x5_3 - three rows of five, and three thumb keys, for each hand). This is a diode-free design with a sparse 13 by 13 scanning matrix designed using a partial Tutte-Coxeter graph (using only 26 vertices or GPIO pins, with 36 edges or keys - see this blog post for background, although the final pin selection and trace routing changed).
The first physical PCB for this was designed using the Gamma Omega keyboard footprint from Ergogen. This is intend use the same Raspberry Pi Pico YD-RP2040 microcontroller board to fit the same 3D printed case, including reset button placement.
- Keyboard Maintainer: Peter J. A. Cock

Bootloader
Enter the bootloader in 3 ways:
- Bootmagic reset: Hold down the key at (0,0) in the matrix (bottom left key, Qwerty
z) and plug in the keyboard - Physical reset button: Briefly press the button on the back of the controller (if physically accessible)
- Keycode in layout: Press the key mapped to
QK_BOOTif it is available
