For context, I’m hoping to make a custom laptop using Rock 5B+. I want to expose the side with most of the IO ports on the side of the laptop. However, the power connector is on that side, so I can’t route the battery power through that.
What options are there for powering the Rock 5B+? I’m aware that you can supply >5V (e.g. 12V) into the USB Type-C power connector, without any special USB PD hardware. I’m also aware that you can give it a 5V supply over the GPIO pins, but the board can draw a lot of current, making connector and wire resistances problematic, especially if I’m using an NVME SSD. Would I be able to power the board with a similar voltage through the other USB Type-C port, the one with DP alt mode? Or is the power port the only one that supports >5V?
I’m also aware that the board has PoE pins, but those aren’t well-documented. If I understand correctly, that only accepts 5V anyway, making it worse than the GPIO pins. Am I wrong? Can I supply a higher voltage using those pins? If so, how?
