Texas Instruments’ DRV8833 is a dual H-bridge motor driver IC that can be used for bidirectional control of two brushed DC motors at 2.7 V to 10.8 V. It can supply up to about 1.2 A per channel continuously and can tolerate peak currents up to 2 A per channel for a few seconds, making it an ideal driver for small motors that run on relatively low voltages. Since this board is a carrier for the DRV8833, we recommend careful reading of the DRV8833 datasheet (1MB pdf). The board ships populated with SMD components, including the DRV8833, and adds a FET for reverse battery protection.
This board is very similar to our DRV8835 dual motor driver carrier in operating voltage range and continuous current rating, but the DRV8835 has a lower minimum operating voltage, offers an extra control interface mode, and is 0.1″ smaller in each dimension; we also carry a DRV8835 dual motor driver shield that is easy to use with an Arduino. The DRV8833 has a higher peak current rating (2 A per channel vs 1.5 A), optional built-in current-limiting, and no need for externally supplied logic voltage.
For a smaller, lower-cost, single-channel alternative to this driver, please consider our DRV8838 carrier, which offers a similar operating voltage range and current capabilities.
For higher-voltage alternatives to this driver, consider our A4990 and DRV8801 motor driver carriers.
