Wow! Thank you for all the work you put into this. This is perfect. Incidentally, your approach of using single row connectors is how their Proto Shield is designed. It routes the pins over and under the board to new pins inside the PCB.
For future reference, the "v3" in the file name is referring to the model of the Mojo (there is also a v2), not the revision of my part.
I have updated the GitHub project with your changes and added the sample sketch to a new folder at the root of the project.
When I update the readme file on the GitHub page, how do I credit your work? I definitely want to give you credit for cleaning this up.
Thanks again for all of your hard work.
