Could some1 with some acknowledgment of these stepper motor give me some advice of what kind I should order, should I go for unipolar or bipolar?
I do know that for a unipolar I need to get a Darlington Transistor Array and for a bipolar I need some H-bridges.
What do you think of this one? http://www.aliexpress.com/product-gs/517614158-NEMA17-78-Oz-in-CNC-stepper-motor-stepping-motor-1-8A-wholesalers.html
Edit: I dont know if its allowed to post links, if its not please tell me
