[TriEmbed] Sanyo Stepper Motor

[Grawburg]

Pete, I spent a lot of time looking and never came across this link. This looks like the correct products.

Yes Jon, I am hoping to use the drivers I got from you.  Using the I/O expander is simply a precautionary step until I'm certain that everything is wired correctly.

If I understand some of what I've been reading about bipolar motors, running it at a slightly higher voltage (i.e. 5) is not likely to cause a problem.

Clearly I will need a level shifter between the controller card and the Raspberry Pi or the MCP23008 I/O expander.  If the controllers require 8 VDC does that mean I will be powering the stepper with 8 as well?
