Unfortunately POE is still external on the Rock Pi 4

A carrier board for Compute Module with just POE / ethernet, USB ports and and SD card slot would be good enough too

I literally want same form factor as the Ubiquiti board but with open source support, and sufficient power to charge a phone from the USB port

Orange Pi Zero is along the right lines but doesn't have enough RAM for my needs and I'm unsure about the processor

This is Tom Cubie, the founder of ROCK Pi. If you want small form factor, we have ROCK Pi S for you. Checkout:

Thanks but that doesn't have enough RAM for me or POE

Basically want something like https://fccid.io/SWX-UCCK/Internal-Photos/Internal-Photos-36...

I network / POE port, 1 or 2 USB sockets to plug a phone into, SD-Card slot, 1GB+ RAM, A53 (or above) processor

I'm OPiZ huge fan!

But 256MB limitation is killing me. Other was Wifi performance and reliability (for non LTS version).

Hmm, PoE support on the Rock Pi 4 seems to be a hat just like the rpi 4.

rpi 4 PoE is only 13W, which is not enough for ROCK Pi 4 with SSD, USB3 etc. We have designed the ROCK Pi 23W PoE.
