20A Unipolar Stepper Driver
This project show you how to build Unipolar Stepper Motor driver for high current. The driver able to handle up to 20A. The main component in this driver is L297. While the driver circuit is more or less taken from the L297 datasheet. More features from the project are : Handles a maximum of 100V, Handles a maximum of 20A, Half-step and full-step, Shuts down on overtemperature, and PMinMO-compatible interface. The project designed by Dalton.
