TLC5940NT Painter Board

This screen shot is an all-layer view of my TLC5940 painter board.  The 1st draft featured two TLC5940s, but I decided it made the board too large.  Instead, I wanted the ability to mount the painter boards around the LED’s shadow box.  This should make routing all the wires much easier.

Quick schematic in gschem running on OS X.

In an attempt to find a free set of schematic and PCB tools for hobby work, I looked back at gEDA. The last time I used it was when the project first started, years and years ago. I was happy to see that OS X had a set of fink packages for the gEDA suite. After figuring out how to get X11 in Leopard (since I didn’t include it when I installed 10.5) and install fink, getting gEDA going was a snap.  The user jluciani in the Arduino forums has provided some free pcb footprints he has used from previous projects.
