# [Clueboard California Macropad](https://clueboard.co/parts/clueboard-california-macropad-kit) |
||||
|
||||
A small 10-key macropad in the shape of the US state of California. |
||||
|
||||
## Features |
||||
|
||||
- Per key LED. |
||||
- Proton-C only, including space for the piezo speaker. |
||||
- Direct GPIO wiring, no GPIO matrix at all. |
||||
|
||||
