From the project

Chording 5 key with 5 layers - full USB keyboard emulation

Cinco-Cinco is a low-profile chording keyboard that uses just five keys to emulate a full keyboard by combining keypresses into chords and utilizing seven layers.

I’ve spent the last year building pocket keyboards. My BUBBY is a daily carry which I use for todo lists. It made me enjoy typing with one hand to the point that I wanted a desktop version, which is what you see here.
