I'm having some issues with the Arduino Portenta H7. I'm making a footprint using their 2.54mm 14-pin headers, but I can't find documentation on exact measurements about how far apart the connectors are from each other.
Using their interactive board viewer is giving me really strange results. Looking at their PCB view, I get different measurements. Taking the object-to-object measurements of the last pin, I get 18.8 mm between the headers. Taking the point-to-point measurements of the same set of pins, I get 20.32 mm between the pins. Taking a look at the datasheet at pages 17 and 18, assuming that the distance of 2.57 mm from the board edge to the center of the header is the same on both sides, I got a distance of 20.26 mm (that's 25.4-2.57-2.57).
All of these inaccuracies are really annoying me. I also found this Grabcad 3D Model that someone posted online, but the pin distances don't seem to match up with the model (which I'm taking with a grain of salt). I was wondering if anyone has any accurate measurements of the Portenta H7 14-pin headers? Can anyone help me with this?
