For AC3.1.5, the pinout of the APM is as follows:

  • A4 : AUX led
  • A5 : Beeper – can drive a piezo buzzer directly (see below)
  • A6 : GPS – will flash with no GPS lock, solid with GPS lock
  • A7 ~ A11 : Motor LEDs

Which LEDs are active and when they blink is somewhat configurable through the LED_MODE parameter which can be set from the Mission Planner’s CONFIG/TUNING > Standard Params > Copter LED Mode drop down.

For AC3.2, the LED_MODE parameter is removed but all the following reduced set of pins are always active:

  • A4 : Motor LED
  • A5 : Beeper – can drive a piezo buzzer directly (see below)
  • A6 : GPS – will flash with no GPS lock, solid with GPS lock
  • A7: Arming LED
