There must be a UART because there's a FT223H and USB port at the top left.

[duskwuff]

For a FT232H on early development hardware, my first thought would be JTAG, not UART. Could be both if it's a '2232, though.

That micro port may only be for power.

Or perhaps a client port to allow a PC to talk to the board without a network connection.

[joezydeco]

Yeah, that's totally a console port. The micro-B device connector gives that away.
