L298N Dual H Bridge DC Stepper Motor Drive Controller Board Module For Arduino The L298
Stepper Controller makes it easy to drive either two DC motors or a
bipolar stepper motor. This is a very high quality board and is very
compact for designs where space really matters.
Connections There is a tutorial here. Library Available here: Stepper Library

/* Stepper Motor Control - one revolution This program drives a unipolar or bipolar stepper motor. The motor is attached to digital pins 8 - 11 of the Arduino. The motor should revolve one revolution in one direction, then one revolution in the other direction.
