stepper motor drivers

<< < (4/4)

Jadecy:
A single G250 for a single axis will work fine. Remember that you will still need a power the supply. The driver board contains the power transistor and driver circuit but does not supply the power to run the stepper motor. The G250 will drive NEMA-17, most NEMA-23 stepper motors according to the documentation on the Gecko driver site. You can just eliminate one highlighted section of the circuit if you just want to control one motor. For the initial build I would suggest getting a breadboard (temporary solderless circuit prototyping board). What a breadboard is: http://en.wikipedia.org/wiki/Breadboard

If you have never done electronics before you may want to get a little project kit that will help you build a few projects to get used to schematics and some basics. I'm not sure what is available where you are but here we have these:

It has a breadboard plus some neat projects to get you headed in the right direction. The preadboard can be used for the circuit I posted. You would just need to purchase a couple extra parts.

Hope this helps!
