A firmware for theClueboard 66% Low Profile keyboard (also knownas 66% hotswap) implemented in pure Rust usingKeyberon.

The Clueboard 66% LP uses a STM32F303 ARM Cortex-M4 microcontroller. It alsohas an IS31FL3731 for controlling white LEDs on each switch, and two speakers.I've not yet implemented support for the LED controller or speakers.

Note: These instructions have only been tested on a Linux host.
