Lightly used (under 24 hours of use) pixhawk (purchased w/ BlueROV2 Enclosure Only Package) last year. At our last demo at a local MakerFaire, the ROV quit working and the heartbeat stop blinking and we lost connection. We have pulled the pixhawk, tried to direct connect to a computer and it’s not recognized. Pulled out a spare and was able to flash the card, replaced it into the nonworking pixhawk and still not operational. With no heartbeat and no USB connection, is the pixhawk dead (even by itself and plugged into the computer), the pixhawk is warm to the touch.
Please advise… is there a reset I can do or tricks to getting the USB to be recognized?
