This is a DIY trackball prototype.
It uses this PMW3360 sensor breakout: https://github.com/jfedor2/pmw3360-breakout and either a 57.2mm or a 38mm ball (I used billiard balls).
In addition to the breakout you'll need some kind of a (3.3V-capable) microcontroller. I used an Arduino Micro.
The buttons are Kailh low profile (choc v1) keyboard switches.
