Sorry, It's late and my wits have started to slip. The above 3 axis
card as well as all of their other cards are UNIPOLAR. They also
talk about current limit power resistors. Sounds like a good one to
pass on if you need the electronic current limiting and bipolar
signals.

When it's all said and done it's hard to beat the good old Gecko 201.
