KeySeeBee (modified from TeXitoi/keyseebee)
KeySeeBee is a split ergo keyboard. It is only 2 PCB (so the name) with (almost) only SMD components on it. It's no longer only a keyboard, it now has keys, USB, rotary encoders, and OLEDs.
The old firmware at Keyberon, a pure rust firmware, has not been ported yet as I wanted more of the functionality that QMK provides without having to code some of those advanced features.
QMK firmware for this version is located here.
- 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 components (except for the switches, TRRS connector, and optional components).
- 2 SPI OLED 128x32 3.3V (optional not SMD)
- 2 EC11 Rotary Encoder (optional not SMD)
- Plate files (optional).
- Plaid for "show the components"
- GergoPlex for "just a keyboard" and "only a PCB with SMD components"
- Lily58 for the thumb cluster
- Kyria for "don't be affraid of pinky stagger"
- keyseebee for initial design without the OLEDs and Encoders and way too many diodes :)
Price is for 5 keyboards including shipping.

Follow the QMK guides using my branch of qmk_firmware (or copy my code, idk)... I might add more specific steps in the future.
Yeah, I'm still figuring it out. I really prefer ZMK and if I can get ZMK working on this keyboard, I'll start using that instead and update the layout here for what I like.
