Unipolar Stepper Motor Driver

Unipolar Stepper Motor Driver

grabcad

A driver board for a single unipolar stepper motor. It's based on the Allegro Microsystems UCN5804 chip, which I think might be out of print, but I've got a bunch of them. The 5804 is good for motors up to 1.25A coil current, and the driver is designed to work with my PIC dev board (PIC16F876 Development Board).
