That's a bit more than docs for a mouse, that's technical documentation for a chip...

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.
Yea this is standard for sharing this kind of info with another company.
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.
They're not the only ones. Foscam demanded I fill out and sign an extensive multi-page developer's agreement before providing 2 HTTP commands to control the siren and light.
What is the context here? What was the original inquiry?
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
Vendor/supplier-only relationships are pretty common in the industry, unfortunately.
But it's SPI, so get a USB logic analyzer and with some LLM help you might be able to reverse engineer the thing. Maybe borrowing info with other Pixart chips?
