Had to make some large revisions to the roboduino board: namely, I had miscounted the pins on the programming header and was using only five pins instead of six and I was using one decoupling cap for both AVCC and VCC, among other errors. The design has been refined. New schematics are available, and soon I will sleep (at 0715 in the morning) so maybe I can design things without such glaring errors.

Full-size schematic available at http://twitpic.com/14jj26.
I quickly laid out a DIP/PTH variant of the design and a TQFP/SMD version of the design, and hopefully by the end of April I’ll be able to pull out prototypes for testing.
