The QMK Proton C is a microcontroller-board, pin-compatible with 3.3V Arduino Pro Micro. Instead of an 8-bit AVR, it uses the ARM Cortex-M4 based STM32F303CCT6 as microcontroller. It was made especially to be used with the QMK firmware.

Description

The USB port is a USB type C, which is both through-hole and SMD mounted. It should be tougher and not as easily torn off as the USB micro B port on the original Pro Micro.

The main part has pads for USB, a +5V output pin for WS2812 LED strips and a physical reset button.

The bottom is a break-away part with 11 additional digital I/O pins not on the Pro Micro and a hole and pad for a piezo speaker/buzzer.
