[oopic] Re: Which Stepper Motor is best?

Before you even start down this path, you need to read "Jones On
Steppers" Google for it.

Along the way you will find the difference between bipolar and
unipolar motors. You will learn about overvolting the motor and
current limiting the winding current.

If you want any torque at all, you need to learn more about the
motors. Or buy a motor driver chip from Allegro. I seriously doubt
that an OOPic could be made to perform all of the functions of a
complete driver chip.

OTOH, you can get a unipolar motor and drive the winding with MOSFETs
(I recommend IRL540N) from the output of the OOPic. It will work. It
won't have the ultimate in torque, RPM or microstepping but it will work.
