As stated in the documentation http://ardupilot.org/copter/docs/common-relay.html
"A “Relay” is an digital output pin on the APM or Pixhawk that can be
switched between 0 volts and either 3.3V (Pixhawk) or 5V (APM2).
Similar to a servo it allows the flight controller to invoke some action
from another device on the vehicle. In Copter, Plane and Rover, up to 4
pins can be defined as relays.""On the APM2, A9 (pin 9) is the pin that is recommended to be used as a
relay. In fact any of the pins from A0 ~ A8 may also be used as relays
but to use these you must manually set the RELAY_PIN parameter (to “0”
~ “8”) through the Mission Planner’s full parameter list.""On Copter 3.2 (and higher) the “First” relay can be controlled with the
Ch7/Ch8 switches."How do I enable ch7 to controls the relay on rover?
Any suggestions?
