Power-LED
A power LED in the casing can be connected from pin 12 to pin 11. The “+3.3V (LED)” supply pin already
incorporates a 330 Ω series resistor.

GPIOs
The GPIO pins are directly connected to the respective signals of the Intel QM57 (“Ibex Peak”) PCH. GPIO 28 is
in the Suspend power domain, the others in the Core power domain (i.e. powered down if the board is
suspended). All GPIOs are 3.3 V tolerant and have 10 kΩ pull-up resistors. For programming examples see
chapter 4.3 unterhalb.

Backup BIOS
In order to recover from BIOS problems, a recovery BIOS can be used. This is a special hardware unit that can
be attached to the Backup BIOS Connector.
