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. The board ships populated with SMD components, including the DRV8833, and adds an FET for reverse battery protection.

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.
