I’m trying to understand what output specs are needed for PoE HATs. The listed POE hats compatible with Rock Pi X do not meet the power requirement for USB-C of 9V/2A. I have other POE hats that fit the 4 pin header on the Rock Pi X with the same output specs of the Official Raspberry Pi HAT - Should they work?
Power over Ethernet power requirements
I stuck a std pi hat on mine and it seems to work just fine for me. Using 5volt on the 5vdc pin
