Hello !! I have a question about the hwvoltage that I can see into the MP status tab.
It indicates a value fluctuating between 4,5 and 4,6V , which seems to me too weak.
Verifying this voltage with a voltmeter ( i.e. on the APM's gps connector) I confirm that
the measure is correct. However , my APM 2.6 is powered by a 3DR power module and I can measure 5,28V on its output , as on the APM PM input. I don't understand why such a drop in voltage into the APM module , and if this weak hwvoltage value could be a problem during the flight. Thanks.
