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
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
