Hi

What was the answer to the following?

I have the same issue where A1 is 18v. I know the voltage from my UBEC to the Servo rail is 5.31v via a multimeter.

As an aside (and possibly related) I believe the PWM is very unstable. I am having difficulty getting a servo to work correctly in python. Its worked once out of hundreds of attempts…
