The Keyboard Controller You Didn’t Know You Needed
At the heart of every keyboard is a controller. It is a computer chip that is responsible for translating your button presses into signals your computer can understand. Many PCB’s have a controller built in (or “Pre-soldered”) while others rely on an external controller. The most popular external controller is a Pro-Micro.
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 availble on the lower half of the Proton C, and can be broken off for builds that aren't compatible.
Because this is a pre-order, if you order this item with any other items, they will not ship separately. If you want your in-stock items to be sent separately, place a second order. Do not order this item with different groupbuy/pre-order product.
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.
