From the project

Another 3x5 Ergonomic Split Keyboard

The VOID keyboard is meticulously designed to offer an ergonomic typing experience with its compact 3x5 layout. It supports a variety of switch types, including CherryMX, Choc V1/V2, and a hybrid configuration.

Similar to the uniCorne, the VOID keyboard features controller compatibility, hardware handedness, and Nice!View integration. Additionally, for communication between each side in wired keyboards using PR2040/ProMicro, it uses a USB Type-C connector instead of TRRS to avoid short circuit issues that can damage MCUs.
