OK, So I think I have figured out most everything about connecting a stepper motor using the Little Step U. However, I have a question I need to get the answer to so as not to fry anything. At the bottom of this page, http://www.parallax.com/Portals/0/Downloads/docs/prod/motors/littlestepuman.pdf there is a schematic of all the connections. My question is, is Vin and VSS on the BS2 connected to ground? I have never seen a Ground referenced that way and I want to be clear about this because the Little Step U is not a cheap item. Thanks for the help.
