The NI page has a spec sheet that says there's a staged brownout from 4.5V-6.8V. Is that new? My understanding is that the current PDB feeds 24V to the cRio, so 4.5V of battery voltage (plus a bit for resistance losses) can meet the 9-30 V power requirement. If that requirement goes up to 6.8 V or down to 3.4 V, that has implications for robot design.
It's connected directly to the PD board battery supply.

I can't find the post but I read that they made it to allow for teams to mess up and hook it up to 24 volts without destroying it.
