SparkFun currently sells the [L298N full bridge motor driver with a [breakout board which is useful for driving DC motors and stepper motors, but using this chip with stepper motors can be made even easier with the [L297. These two chips work so well together that they actually mention each other in their datasheets. The L297 is available in a DIP with standard .1" lead spacing. It has built-in chopper circuitry, and it support full- and half-stepping. When the L297 and L298N are combined, driving stepper motors is made very easy.](http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/CD00000063.pdf)](SparkFun Full-Bridge Motor Driver Breakout - L298N - BOB-09540 - SparkFun Electronics)](Full-Bridge Motor Driver Dual - L298N - COM-09479 - SparkFun Electronics)
