GAMMA OMEGA
A 36 Keys low-profile unibody ergonomic keyboard designed for portability and durability while still maintaining comfort.
Portable? It may not be very compact, but you can still just toss it in your bag, right?
Variants
There are currently three variants of Gamma Omega in this repository, all using the same 36-key layout and spacing.
| Controller | Connection | PCB | Diodes | Roll-over | Switch | Built | |
|---|---|---|---|---|---|---|---|
| Original | Raspberry Pi Pico | USB | Twin | 36 | NKRO 🥇 | Choc v1, v2 | :white_check_mark: |
| TC36K | Raspberry Pi Pico | USB | Mono | 0 | 6KRO 🥈 | Choc v1, v21 | :white_check_mark: |
| Hesse | Nice!Nano v2/clone | USB/BLE | Mono | 0 | 4KRO 🥉 | Choc v1, v2 | :white_check_mark: |
The original and TC36K versions use the same case. The Hesse has a Bluetooth capable MCU controller and a slightly different case for the battery etc.
See the README.md in each folder for more information.

SPECIAL THANKS
- This project was greatly inspired by his work. In particular, TOTEM. TOTEM is my favorite lo-pro split keyboard. Please check it out.
- Thanks for creating and contributing the TC36K and Hesse variants.
Contributing
Contributions are welcome! Feel free to submit pull requests or open issues for any improvements or bug fixes.
The repository uses git-submodules for some footprints, it can easily be setup locally with:
git clone --recurse-submodules https://github.com/unspecworks/gamma-omega.git
But I don't know much about modeling and PCB design.
