MegaSquirt-II Photos

These pictures are of one of the two original MS-II prototype boards. The current production boards differ in several details, but the overall physical layout and dimensions are the same. The board is 70 mm long and 28 mm wide, because someone asked.

This is a shot of the MegaSquirt-II installed on a V1.01 MegaSquirt board.

Here is a comparison of the original 908 processor and the MegaSquirt-II board installed in its place.
