Is there a mechanical drawing that shows all the features of the BB in a
single document? The SRM shows ome features but they are scattered all over.
Prehaps a DXF of the PCB showing the mountinghole location locations, the
connectors (both expansion and the RevC LCD)?
No there is not. There are the Geber and Allegro files that can be used to get dimensions. I iwll look at adding this in the next release of the SRM.
