Supplying power through GPIO 5V or POE connector

ROCK 3 Series
1

Hello,

I would like to power a few RockPi 3A from a single power supply to avoid unecessary waste.
Is is possible to supply enough power via both 5V pins (pin 2; pin 4) on GPIO (I am aware that they might not be fused, similar to what is done on RPI3/4)?

I havent seen any reference regarding the pinout of the “POE” connector (between the GPIO and the USB2) which is used by the PoE hat. Can someone point further information about it?

Thanks

Yes, it can supply power from pins 2 and 4, with a maximum carrying a current of 5A.

Thank you for the info.

Is it possible to disclose the pinout of the PoE header on the board?
I found no reference to it in the drawings published.

Looking in the pictures of the PoE hat, the thickness of the traces looks to me the connector is used to supply power. I’m curious if is possible to use higher voltage (12V as it matches vcc in?) to use a common PSU across different boards (Taco, Rock 5 …).

Thank you in advance.
