I'd guess at the 4-pin connector above the micro-SD card, to the left of the screen-print part number.

I'd guess it's that four-pin connector to the right of the Wifi card, and to the left of the board ID number on the silkscreen.
You'll need a meter to confirm which is GROUND/GND, which is +5VDC (or +3.3VDC), then the other two are RX receive data and TX transmit data.
