      Hello,

      We're seeing a problem with the power module v3 and multiple VOXL Flights. We get the error "avionics power low 4.79 Volt", and have seen this on multiple power modules connected to multiple VOXL Flights and Flight Cores. We've seen voltages reported as low as 4.72, but other times it's absolutely fine without any error.

      Specifically, we're using the Power Module v3 with a VOXL Flight in this case, powered by a 6S battery. It's often fine, but will randomly throw the error "avions power low".

      Most recently, we swapped out the power module on this system to address it but are still getting the same error. We had also seen this same error with the same power module and a different VOXL Flight unit, so we've now seen this across two power modules and two VOXL Flights.

      Any thoughts as to what's causing this? I'm skeptical multiple units could be malfunctioning, could it be a software error in PX4?

      Appreciate any help on this!

        @Ansel-Misfeldt said in Avions power low warnings:

        avionics power low

        FYI: We normally set CBRK_SUPPLY_CHK to 894281 to disable this check
