Stepper motor controllers are more complex than DC motor controllers. Driving a bipolar motor with microstepping requires 2 complete H-bridges and 2 channels of PWM.

The versatile Adafruit Motor Shield V2 has 4 H-bridges and can drive as many as 2 steppers. What's more, it is stackable to control dozens of motors.
For more stepper motor control options, see the "Driving a Stepper" page of our "All About Stepper Motors" guide.
