The Bit-C is a microcontroller daughterboard featuring the Atmel ATmega32U4, designed for DIY keyboard enthusiasts. It features a sturdy through-hole USB-C connector that is more rugged than a standard USB micro B. It’s only 1mm thick, so it sits slim and low. The Bit-C ships with the Atmel DFU bootloader, which is smaller and less finicky than the default Caterina bootloader. 100% of Bit-C units are exhaustively tested before shipping, ensuring you’re spending your time building, not debugging. Best of all, it comes in white!
The Bit-C is a drop-in replacement for any Pro Micro MCU, including the Elite-C. With 1-1 GPIO pin parity, firmware builds don’t need to be changed in order to swap in a Bit-C. The Bit-C is shipped with the lightweight Atmel DFU bootloader, making flashing with QMK a breeze. VBUS detection & backdrive protection are implemented for split keyboards, and a 500mA resettable fuse is included for protection.
