I've made available a nearly complete BeagleBone Fritzing part that
supports both breadboard and schematic views.
Grab it from https://github.com/ohporter/fritzing-parts/
There's also a "Getting Started" write up on my blog at
http://goo.gl/OzXph that shows an example of what you can do with it.
Hopefully others find this useful and document their projects with it.
