Re: Voltage drop normal?

The LEDs are usually hooked into the nonregulated portion of the PD board. They are gonna dim when the battery is under a load. That's the reason for the Dim.

The Log viewer, if you are using the most recent update, will give you a wealth of information.

Jaguars require 5.5v to completely reinitialize so if you are dipping really low,there's another problem.

Quote:
(Exerpted and edited from Jaguar documentation)
Supply voltage range (VIN) Min 5.5a
Under-voltage detect threshold – 6.0 – Vdc
a. Power supply requires VIN ≥ 7.0 VDC to start up.
And never slam the throttle. I shake my head when I see a robot reboot cause of a brown out. If you see a dim, and the CRIO or Radio reboots, slamming the throttle back up will put you into another reboot. If I had a nickel for every time I had to tell a team to ease up the throttle so their robot works, I'd still be in FIRST.
