Pololu A4983 stepper motor driver.

This is the board used by the RAMPS RepRap electronics.

This brilliant little board will drive stepper motors up to 32V and 1.5A (2A with a small heatsink). That covers most motors that you'd want to use on a RepRap, including all the ones on our site. You can drive it at 12V and it works fine. More voltage will simply allow higher maximum speeds and more torque at high speeds.
