ZMR250 v2 Build – Part 8 – FC Power Connection

Initially I hooked up power to the Flight Controller from the 'BEC' and 'GND' pins next to the FC but this didn't work..... the reason..... the BEC pin is designed to take 5V from the ESC BEC which of course I don't have because I'm using the LittleBee 20A ESCs which don't have a BEC.

The alternative is to use the 5V regulator built into the PDB. Oscar Liang's web page has some excellent diagrams showing the layout and connections of the ZMR250 v2 PDB.
