DRV8833 Dual H-Bridge Motor Driver Module
The DRV8833 Module is a two-channel H-bridge motor driver breakout board that can be used to drive two DC motors or one stepper motor. It has a total of 12 pins, four of which are output and four of which are input. Each output can supply up to 2A peak current with internal limiting, with overcurrent, overtemperature, short-circuit and undervoltage protection.
