- Moved the fourth standoff mount hole to line up with the Uno's new fourth standoff hole (which they didn't make aligned to the one across the way!).
- Fattened up the traces to make it more home-etcher-friendly: .016" and .024" traces, .018" min. separation.
- Spread out the components, reduced the jumper count, and removed the I2C header.
- Added pads for a mini USB jack, for power only. (I'm not sure about the grounded heat sink of a 7805 shorting to the 5V trace so I put in a solder bridge, but it's fine for making at home using real wires for the top layer jumpers.) So many options for powering this sucker!
Thinking about running this at 3.3V, I don't think it would work right for programming or for running with the FTDI cable attached.
Update: I had some v.97 boards made (DorkbotPDX order ftw!), same as .96 but with curvy traces and a few parts moved a little, here's one assembled:
