Hey Mr. Dan, Seth here. Yep. That 5v only stays on. That black connector is rated at 5v and 3.3v. It does not power off either. See here:
[image: Power.JPG] Seth P.S. From what this fellow told me, those two connectors are used for power but that neither powers down if power is still applied to the board.
