For the second board design we decided to get rid of the individual RGB color strips (all the same color) so we could get rid of the high current transistor drivers on there. Instead we would be using a WS2801 controller enabled LED strip so we could control all the pixels individually.

A 3D rendering of the final connector board design that hooks up to the Olimex STM32 board can be seen below. The schematic and BOM list can be found as the System Design document in the side.
