Arduino

Today I’ll be working with a BIG stepper motor. I'll show you how to use a microstep driver module and an Arduino to drive a NEMA 23 size motor.

This motor is a NEMA 23 size beast that takes up to 4.2 amperes per coil, more than we can drive using the drivers and H-Bridges we used earlier. To drive this motor I'll be using a microstep module, a common device available on eBay, at Amazon, and at your local electronic and electrical supply store. The module I used is a model MA860H but the wiring and coding will work for any one of these modules. In order to select a module suitable for your stepper motor you will need to know how to read and interpret some of the stepper motor specifications, so I’ll cover that. One spec that fools a lot of people is the voltage rating, I'll explain why the number in the
