LEDs

There are four LEDs available on the board that can be turned on and off. Two yellow LEDs, one green LED (power indicator LED) and one red LED (status LED). The green and red LEDs are inside the same package and therefore the colors can be mixed to orange when both are activated. The yellow LEDs and the red LED can be activated by driving the connected I/O line to GND. The green LED is controller via a FET and is by default on when the board is powered. However this power indicator LED can also be turned off by driving the gate of the FET to GND.
