Collection thread:U1 Top-Cover Mod

This is for plugging in a USB drive to copy the machine’s local time-lapse videos.

Ok thanks. The “Add-on” pinout as well, not just the USB port? I’m wondering if the “Add-on” pinout can be used to trigger a fan or other but I don’t see any specs on it.

I did everything you said, it activated, the RPM shows no problem, but my only issue is that the PWM speed adjustment doesn’t work. When I plug it in, the fan stops, and when I remove the blue PWM indicator, it only works at one speed. Do you have any information about this? Can you help me?
