I’m designing a cape for my BBB which should mate with a 2x2 pin header soldered into TP5/6/7/8, as well as the main connectors P8 and P9. In the system reference manual, exact locations are given for P8 and P9 relative to the standard cape board edges, but I need to know the location of the battery TPs relative to some (any) other datum, e.g. the offset of TP5 relative to P9 pin 2. I don’t have commercial CAD or PCB layout software to open the original design files. Could someone give me a measurement (preferably obtained in software, not by attempted measurement of a physical board)?
