powering omega from the expansion dock header
Does applying 5v to the 5v pin on the expansion dock have the same effect as applying 5v to the micro USB port? I am enclosing an Omega in such a way that there is not room for a USB cable connection. I could buy a bare micro USB plug and wire to that, but it will be easier if I can just apply 5v to the header. I didn't find a schematic to see if the expansion dock pin is simply a pass-through of the USB power or if I'll end up on the wrong side of a regulator.

Yes. Regarded by the schematic each VCC_5V point of the board is joint.
Be careful. In this case you should avoid to use the serial connection (via the micro USB port) due to back-powering the USB port of the host PC.
Please correct me if I'm wrong because I don't have any genuine Onion Expansion Docks.
Thanks. Where did you find the schematic?
