The debugger versions are 60mm x 140mm, the production versions are 60mm x
60mm. They are pin compatible (although obviously the debugger module takes
The pictures on the page show each type.
In some cases, it would have been possible to make even a smaller module. The
catch is that we try to make our modules largely pin compatible. Since some
have FPGAs or MCUs or larger FSP packages, the 60mm x 60mm size is practical.
We also opted for 2mm headers so that the companion boards can be less
expensive and easier to layout. The DSP boards require more layers and finer
pitch. We also have addressed some of the trickier design problems such as
