Minimal*duino V.96

I've done a little work on my "Minimalduino" Arduino-compatible board design lately:
  • 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!
Files can be found here.

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:
