Adafruit DRV8833 DC/Stepper Motor Driver Breakout Board

The Adafruit DRV8833 is a dual H-bridge motor driver breakout, capable of driving two DC motors bidirectionally or one bipolar/unipolar stepper motor at up to 1.2 A per channel. It's well suited for low-voltage applications, operating from 2.7V to 10.8V motor power.

The DRV8833 features built-in kickback diodes, eliminating the need for external flyback protection. Adjustable current limiting is included — set to 1 A by default, but configurable or disableable. Two digital inputs per H-bridge allow PWM speed control. Motor voltage and logic voltage share a single supply, but logic levels of 2.7V and above are accepted regardless of motor voltage.

Key Features
