The cap in the upper right is the .1uF. The power for the board comes in on the ribbon cable. The red wire is the ground and you can just make out the +5 wire just above it. Vcc for the TPIC is the red jumper wire right between the cap and the power in from the ribbon cable on that power rail.
Here's another view from the other side. The clear gunk all over the place is hot glue. The wires from the ribbon are very small, so I wanted to give them a little strength. All four of the boards are wired the same.
