Logitech G502 schematics

If anyone has them it should be worth uploading them because these mice (especially the g502 proteus core and proteus spectrum with PWM3366 sensor are starting to fail a lot; new ones with hero 16k sensor must have different pcb/schematics).

I have mine since 2014 and i've fixed it a couple of times; first side switches broke, then side switches board trace, then main mouse switches, then sensor board. But all is fixable.

Example in the optical sensor board a resistor failed partially in MISO serial output, making the mouse jump all over the place. I bought a donor board to find the issue since the resistor read 1.2K instead of 150ohm.

If i had datasheet from the start i wouldn't need to buy donor board; sometimes parts are hard to find. So please share to help others :)

Attached datasheet for PWM3360 sensor (very very similar to PWM3366, only internal differences between them)
