I have been trying to make things and put items of interest together. With some help from #beagle at Freenode and with the book "BeagleBone by Example (Prabakar 2016)," I have come to a conclusion.
The conclusion I have come to helps the older Cape from Seeed-Studio, i.e. The Motor Bridge Cape. I first got ideas to work with this Cape many years ago.
Last but not least:
I think that should do it.
P.S. If you have any questions, please dedicate any ideas, feedback, or other communications to me (Seth).
