KeySeeBee is a split ergo keyboard. It is only 2 PCB (so the name) with (almost) only SMD components on it. It's only a keyboard, no LED, no display, nothing more than keys and USB.
Features
- Fully opensource, under the MIT license;
- 44 keys, using Cherry MX or Kailh choc switches, only 1U keycaps;
- USB-C connector on the 2 sides;
- TRRS cable for connecting the 2 halves (for power and UART communication between the 2 halves);
- 2 STM32F072 MCU, with hardware USB DFU bootloader and crystal less USB;
- Only onboard SMD component (except for the switches and TRRS connector).
The firmware is Keyberon, a pure rust crate (library) giving all the needed tools to construct your firmware. It is used in several keyboards, and not only mines! It is now published on crates.io as v0.1.0.
