Check out the "jumpers" and their functions on the IdeZilla page. This
circuit board has an adapter on the front of it. It requires a short cable
connector on this board to work, ie strap both headers together, this could
be done with wire staples. This adapter can be cut loose and used to extend
this main board to another location, ie farther away. The main board can
be used separately to connect to the "bottom" header here on this site.
The cable that would be the extention cable will have it's rows swapped,
this is OK! This board is made for this row swapping, especially if someone
uses that "bottom" connector scheme.
