LEDs

There are four LEDs on the SAM3N-EK board:
A blue LED (D1), a green LED (D2), and an amber LED (D3) which are user-defined and controlled by
the GPIO.
A red LED (D4), which is a power LED indicating that the 3.3V power rail is active. It is also controlled
by the GPIO and can be treated as a user LED as well. The only difference with the three others is that
it is controlled through a MOS transistor. By default, the PIO line is disabled; a pull-up resistor controls
the MOS to light the LED when the power is ON.

ZigBee

SAM3N-EK has a 10-pin male connector for the RZ600 ZigBEE module.

4.3.16 PIO Expansion
The SAM3N product features three PIO controllers, PIOA, PIOB and PIOC, which are multiplexed with
the I/O lines of the embedded peripherals. Each PIO Controller controls up to 32 lines (15 for PIOB).
Expansion ports J5, J6 provide PIO lines access for customer defined usage.

0 Ohm resistors have been implemented in series with the PIO lines that are used else-
where in the design, thereby enabling their individual disconnection, should a conflict occur
in your application.
