I have milled these boards in iModela. I mounted the components on the boards. The boards work well.
After I have loaded the program in the three boards.
I tried to use the cable with a old parallel cable. But this has not worked. I added my connector cable
other connection between the two nodes and the bridge.
I have used Ubuntu to load the python program that controls the boards. I changed the program to each
of the boards and I have proven that they work.
Enclosed is a short video of this exercise (https://vimeo.com/65142844).
