81 keys in a 9x9 grid
- Pro Micro using all available pins
- Hand wired
- TMK firmware
- Gateron switches
- DSA keycaps from PMK grab bags
- 3mm laser cut top and bottom
- M2 nylon spacers and screws
I have no real use for it. It sits on my desk at work as a paperweight.
I suppose you could use a keycap puller and actually play sudoku on it.
