This tiny breakout board for TI’s DRV8838 motor driver can deliver a continuous 1.7 A (1.8 A peak) to a single brushed DC motor. With an operating voltage range from 0 V to 11 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering a small, low-voltage motor. The carrier board has the form factor of a 10-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1″ perfboards.

Texas Instruments’ DRV8838 is a tiny H-bridge motor driver IC that can be used for bidirectional control of one brushed DC motor at 0 V to 11 V. It can supply up to about 1.7 A continuously and can tolerate peak currents up to 1.8 A for a few seconds, making it an ideal driver for small motors that run on relatively low voltages. The DRV8838 is a great IC, but its small, leadless package makes it difficult for the typical student or hobbyist to use; our breakout board gives this driver the form factor of a 10-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1″perfboards. Since this board is a carrier for the DRV8838, we recommend careful reading of the DRV8838 datasheet (1MB pdf). The board ships populated with SMD components, including the DRV8838, and adds a FET for reverse battery protection.
