968 developed a LED driver board that uses small power transistors to switch our LEDs. This allows us to drive multiple LEDs(5 of them) without going over the PSoC limits.

My team is looking at wiring up a LOT of LEDs to its OI. I know the PSoC board is presently jumpered to give 5v and the LEDs are being driven directly from the digital outputs (I don't think from the high current (HC) ones). They're also looking to use some super-bright LEDs that I'm sure exceed the current-sourcing limit of the PSoC board.

So my real question: what is the BEST solution for wiring up a lot of LEDs on the OI?
