Perhaps the iTead Studios bare Duemilanove, MEGA 1280, or Nano 3.0 boards would be close enough?
Actually that board is even better because it has a thru-hole crystal rather than an SMT resonator.
What I want to make is an AVRISP. I already made one with a proto-shield and a ZIF socket, but using a bare Arduino board with simply the reset pin moved will be a much neater package (no ugly wires all over the place).
Thanks again... that's exactly what I needed!
(edit to add):
I did some measurements to see if a ZIF socket would fit and it seems as though it will:
Of course, I don't need any components other than the crystal and two little capacitors (both of which are well outside the socket footprint).
Thanks again for the link!
