Using the board

The board can not be powered from your mobile phone, you will need to supply 5V on the 5V header pin. This will also charge your phone.

This board is compatible with AOA (Android Open Accessory), and for example the PodMode app.

Pinout

The 12-pin connector is connected as follows:

5V	3V3
USB ERROR#(jumpered)	TEST0
IOBUS6	IOBUS5
IOBUS4	IOBUS3
IOBUS2	IOBUS1
IOBUS0	GND

LEDS

• The only LED is a power LED

Jumper settings

• The jumpers are, from left to right, for CNFG2, CNFG1, and CNFG0. Placing a jumper connects the config pin to GND, removing it leaves the pin open. Please see the datasheet for the correct jumper settings.

Future hardware enhancements

• jumper to be able to disconnect the 5V header pin from the 5V USB pin
