QMK Compatible trackball - mouse sensor PMW3389 Board

This fully assembled sensor board arrives tested and everything soldered! Simply solder wires and add the necessary code.

I've had to rebuild the Ogen design to solve issues with newer production date pixart sensors. As a result mounting point have changed.

Well loved and supported this trackball / mouse sensor functions easily with QMK. Providing solid tracking at a good price the PMW3389 can be used in split keyboards with one or even 2 on a board!
