Hey all -
I've got an arduino controlling a small stepper through a ULN2803. Works fine for just playing around.
I was looking at driving a larger stepper and thought about using TIP122. Now if I know the max current per coil of the stepper, and that value does not exceed the capabilities of the TIP122 then would this approach work?
What are the downsides of this approach?
Thanks!
