Keyball39

Keyball is a family of keyboards that feature a 34mm thumb trackball with the widely used PMW3360 sensor. In partnership with Yowkees of 

Shirogane Lab, the creator of this wonderful integrated trackball design, we're happy to bring Keyball to a wider audience.

The trackball sits in an injected molded housing with 3 ceramic bearings. The ball slides snuggly into the housing and moves smoothly in all directions thanks to the bearings.
