The SN754410NE from Texas Instruments is a quadruple half-H driver that can be used for bidirectional control of two DC motors or to control a single bipolar stepper motor. You can use this item as a replacement part, to stack on an existing motor controller, or to make your own motor or other high-current device controller.

This integrated motor driver has the same pinout as the L293 that is popular in robotics applications, and the SN754410NE has the additional benefits of built-in protection diodes across the power transistors and output current capability of 1 A per driver. For even higher current applications, it is possible to physically stack two devices on top of each other to get almost 2 A of drive current, though we recommend you use a higher power driver in those cases, such as the DRV8835 dual motor driver carrier.
