Boards came in. They'll need some tweaking, but they look pretty cool.

I made some changes and pushed everything to github.

It is probably now functional but untested. It appears to fit good over printed full scale prints from the NI website. There may be some interference between Arduinos with full size USB ports and the solder joints for the RoboRio connector. I'll make another revision if that is the case. I broke out 4 PWM lines also this time.

Pics of the prototype. I guess this project will get shelved for a while. There aren't any beta teams very close.
