First of all I have not used this particular adapter. All the similar adapters I have used get their power from the USB connection and have a jumper to select between 5v and 3.3 volts for the RX and TX interface. Looking at the picture of the board, I cannot see a jumper. As the Pocket Beagle is 3.3 volts only, I suggest you connect the Pocket Beagle 3.3 volts ( P1 pin 15) to the 3.3 pin on the board. I would not connect the 5.0 volts.

The layouts I have seen have the TX,RX, GND on the adapter connected to the PocketBeagle RX,TX,GND but when I plugged the usb into my laptop nothing happened. Does anyone know if the 3v and 5v pins on the adapter need to be plugged in and how do they connect to the PocketBeagle(which pins (P1p14?).
