5v brownout (different that RR supply brownout)

[de_]

we did blow out the roborio and tape up all openings at the regional. At the end we removed it and opened it up and saw no issues like debris. We did find a slightly out of position pin on the Ethernet socket.

No amount of deliberate vibration could trigger the message. The robot was dropped 3 times from 6" high powered on, then driven on the field at lunch deliberately crashing into field walls. So its not a vibration triggered (or permanent) short. The robot and its sensors appears so far to operate normally in spite of the message.

I am hoping NI will come up with a list of every internal device internal & external that uses the 5v rail. Perhaps the Ethernet link uses it too. It would be nice to know if the pwm signal is generated off the 5v rail as we have 10 speed controls, any one could be putting an excess load on the signal line and hence the 5v rail due to some type of internal problem.
