SAM4S-EK2 User Guide
LEDs
SD/MMC Card
ZigBEE
There are three LEDs on the SAM4S-EK2 board:
Figure 4-21. LEDs
The SAM4S-EK2 has a high-speed 4-bit multimedia MMC interface, which is connected to a 4-bit
SD/MMC micro card slot featuring a card detection switch.
Figure 4-22. SD Card
SAM4S-EK2 has a 10-pin male connector for the RZ600 ZigBEE module.
A blue LED (D2) and a green 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 two 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.
Note:
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.
