Developed by the QMK collaborators, the Proton C allows you to upgrade any Pro Micro compatible keyboard kit to take advantage of a robust USB Type-C port, a faster Arm chipset, and an optional speaker. Extra pins are available on the lower half of the Proton C, and can be broken off for builds that aren't compatible. Also a great starting point for hand-wired boards!

Includes a 5V step-up output for WS2812 LED chains (rest of board is 3.3V), and a reset button to put the MCU into the bootloader mode.

$2 of every sale goes to QMK.
