Latte Panda Alpha dimensional drawing

Is there a detailed drawing of the Alpha with dimensions showing the board size, hole locations and the location of the expansion header sockets?

Looking at my Latte Panda Alpha boards expansion headers and they don't match up with the 3D models expansion headers. The pitch in the middle of each socket is 2.94mm instead of 2.54mm.

I need to make a PCB with header connections and want to be sure I have the pitch and position of the holes. the 3D models corner holes are correct. The expansion is complete wrong.
