Avionic supply low - 4.9V

#1

Hi guys,

My BEC power module supplies a stable 5.25V to my chinese PixHawk 1. In QGroundcontrol I got the Warning Avionic supply low 4.9V, with and without ESC connected when I try to arm.

Any idea if this is a hardware issue or something else ?

what else do you have plugged into your Pixhawk? Sometimes this low voltage measurements happens if you are trying to power too many things off the 5 volt rail and your BEC can’t keep up.

got gps and rc receiver only. I can actually arm and fly but feels like its not a very good idea. Every time I look at the flights log I got this warning
