Relay switch on Rover


In the documentation:
is mentioned that the relay function is only available on ArduCopter? For my new project I will need a relay switch on a Rover. What would you recommend doing? Installing ArduRover and look for a workaround or just instal Arducopter and chang all the parameters to work on the rover?
the Rover needs 4 PWM outputs: 1 for the main motor, 1 for steering, 2 for a robot arm.
1 Digital output to control a relay.
Any sugjestions?

Hi @kilianderoovere,

Sorry for the delayed response!

1 Digital output to control a relay

You could operate PWM pin as GPIO. This guide might help you to set it.

Please keep us posted about your results.

Hi, thanks for the link, will the GPIO pin be controllable over missionplanner or only from the raspberry pi terminal in this case?
