Did I just fry my flight core?

  • I inadvertently connected a 19V supply to the Barrel Jack on my Voxl m500 drone. What are the odds I only damaged the power module and not my flight core? Are there any easy ways to check?

    On older drones where we have a V2 power module with barrel jack access port for the flight controller, the maximum that can sustain is 5.5V (5V +/- 10%).
    It is very likely you exposed several circuits on FlightCore to a condition much worse than absolute maximum and I would expect either outright failure to operate or worse (fusing/smoking). If by chance your hardware still works, it likely has a latent defect that will fail later. In my honest opinion, I would only power it on outside in the event of fusing/smoke, but would tag it and recycle it or use it for a mechanical reference.

    The power module is still likely OK. Most components on that design allow operation above 20V.

    Hope that helps.

    @jskard Would it be possible for you to please open up new forum posts for these new questions so that they can be better tracked? Thanks!
