I do more electrical engineering on a day off than a day of class

Buck Regulator (12V LiPo to 5V for the PandaBoard):
And color-coded both to make it easier when we’re mucking about in the airframe (lots and lots of wires)”
Jacob and Michael (fellow aerial robots club circuit wizards) did the board designs and sourced/ordered parts. Speaking of those guys…
Dudes, double check component sizes when ordering and change the schematic (if needed). Theres definitely an F size tantalum cap on an A size footprint, so i just had to tack one side down to the middle of the ground plane. Also, on the PoE injector, only one side had room to make mounting holes (for the connector). Lastly, on the mounting holes on both, could you mark those with X’s somehow next time? it makes hitting them with a drill a LOT easier. Thanks 
And the schematic for the Buck reg didnt have component values, I had to reverse-engineer the Bill of Materials we ordered from to figure out what goes where.
