From the project

ZimaCube PiKVM HAT - Raspberry Pi 4 HAT for PiKVM with ATX control, fan control, and status LEDs

A Raspberry Pi 4 HAT for PiKVM that provides full ATX power control, LED monitoring, and fan control for the ZimaCube. Designed by Wayward Signal Systems.

DO NOT connect a standard USB-C cable (with 5V/VCC intact) between the Pi and the ZimaCube while the HAT is providing power via J3.

This HAT supplies 5V to the Pi through the GPIO header (pins 2/4). If you also connect a standard USB-C data cable to the Pi's USB-C port for OTG/KVM functionality, that cable will carry a second 5V source from the ZimaCube's USB port. Two competing 5V supplies will back-feed into each other and can damage…
