Flipped FFC connector on PCB.
Flipped FFC connector (part J3) on Scoutfly so that mating side faces
out from edge of board. Rerouted wires connecting to J3 to accomodate
this. Because the connected ports don't line up as well as they used to,
the area below J3 has a lot of roundabout paths and layer switches. I
think this is about as elegant as that area is going to get without
majorly shifting wires around further down on the board.
