Thanks Eliot - for the response on the light Pwm duty cycle I posted the the specs on the the led driver I am using post before.
I went on a wild chase with the software last night and basically install every single one to make sure I was not going crazy but when I did the Pixhawk1-1M it kepts giving me an error too after it installed but kept say I should use the frmuv2 intead of the -1M.
Only way I got it to work again without any error was go back to the 4.1.2 (Fmuv2) ,which calmed me down because I was on a nervous breakdown.
That depends on what’s connected to it, how much current it draws, and whether the output voltage is outside the range of the components you’re connecting.
We normally recommend using a 5V 6A BEC inside our vehicles, which is used to power a Raspberry Pi + a flight controller board + a camera tilt servo.
That parameter has been removed in recent ArduSub versions, in favour of just directly specifying the type of each servo output. You may need to install a more recent QGroundControl version which knows about the more recent parameters.
