PAW3395 Sensor Board

$22.50
Connector

This is a prototype V1 design! I've validated for a couple of weeks and everything seems working but I have a couple improvements I need to get pushed. Photos and design will be updated once I make these changes. 

A fully assembled, tested PAW3395 trackball sensor board. The PixArt PAW3395 is one of the best sensors on the market right now, tracking up to 26,000 CPI and 650 IPS.

It's built on the same board design as my PMW3389, so it fits the same mounts. Made for the Skree Pawpaw and Cosmos wireless Lemon builds, or your own design.

Includes: a plug-and-play kit: 1 sensor board, 1 lens and 1 cable (dual-sided JST-SH cable, or flexible ribbon cable for VIK, depending on the version you pick).

PixArt keeps the PAW3395's register tables under NDA, so I can't publish what you'd need to write your own driver. PixArt is easy to contact if you want to go that route.
