OK, I think I finally have it nailed down.
I worked with it in Fritzing and was able to line up some ICs to the pins on the Mojo.
I think everything is where it should be. I put the mounting holes on the silkscreen layer. The drill holes should be in the SVG, but they’re not showing up in Fritzing’s PCB view.
The newest Part file is located on my fritzing-parts GitHub page.
