Here's V2, fabbed and assembled. It came in slightly larger than V1, but not by much. It uses the same 6 pads for programming and reading out the EEPROM. This is a 2 layer board, and the only reason it's not smaller is because of the routing. If I made a 4 layer version, I could probably cut the size in half. Although at this point, I don't know if there would be much to gain from going even smaller.
