Im in way over my head as far as the electronics stuff (Im learning a lot,
though), and Im not sure if I understand correctly but if this is a card
that can drive both steppers AND servos [not simultaneously, in my case
anyway] then I would want one for sure, possibly two. How much more would it
cost assembled?
