Figure 4-10. LEDs
SAM3U-EK carries one TFT/Transmissive LCD module with touch screen, FTM280C12D, with inte-
grated driver IC HX8347. The LCD display size is 2.8 inches, with a native resolution of 240 x 320 pixels.
D2 and D3 green LEDs are user defined and controlled by the GPIO.
D4 red LED is a power LED indicating that the 3.3V rail is enabled. It can also be controlled by the
GPIO (by default, the GPIO is disabled and an on-board pull-up to 3.3V lights the LED).
