I’m preparing to replace the PWM control of my gimbal to MavLink.
I’m using the ADSB-IN carrier board - and there aren’t too many free ports. GPS1 and GPS2 are both free - and using the following link as a reference, it looks like GPS2 is the best option - addressing it as serial4 in the parameters.
Do I have this about right? I’d appreciate guidance if I have this wrong.
