Note that all signals marked with asterisk (*) are multiplexed with signals of the Arduino platform.

Those signals can be controlled by the provided jumpers. However, the jumpers are soldered by

default which enables them on the GPIO connector and the Arduino shield at the same time.

PG11, PG13, PG14, PG16 and PG17 are multiplexed with the UEXT and the Ethernet. Their

connection is not controlled by jumpers.

6.9 PWR Jack

The power jack used is the typical 2.5mm one used by Olimex in most of our products. You should

provide between 6 and 16 volts @ 1A to the board.

More info about the power supply can be found in chapters 2 and 5 of this manual.

6.10 Battery connector

When using the battery connector keep in mind that it is an energy solution that wouldn't be able to

power the board and all the peripherals!

It help keeping information in the processor if you need to transport the board from one power

supply to other.
