Well, figured, but it’s not like someone’s gonna “pirate the chips” (and some people in a sweatshop can figure out a way to clone them anyway). Most of the time whenever I want to read a datasheet, I go to some site that sells components, look for anything in mention of PDF and then hope it’s not just useless (to me) graphs like resistance of some data line with ground to temperature.

here, the datasheet button links to a form

Also, that’s not even the correct picture there, that’s for the plastic insert that goes with it

Well, that chip is the sensor. But also a microcontroller that has USB… So basically it’s mouse-on-a-chip. Mine only has that and the RGBs for the entire board.
