DRV8833 2 Channel DC Motor Driver Module

DRV8833 2 Channel DC Motor Driver Module is a highly efficient and compact solution for controlling two brushed DC motors or one stepper motor. Utilizing the powerful Texas Instruments DRV8833 IC, this module provides two full H-bridges, which gives you precise control over the direction and speed of your motors. What truly sets the DRV8833 apart is its remarkably low operating voltage range, allowing it to interface directly with small, low-voltage motors and battery power sources often found in portable electronics and small-scale robotics. Engineers and hobbyists choose this module because it delivers a continuous current output of 1.5A per channel (with peak capabilities) and includes built-in protection features, ensuring both reliability and the longevity of your components. Power your next miniature vehicle or robotic arm confidently with the DRV8833.

Key Features:

• Dual H-Bridge Driver: Easily control the speed and direction of two independent DC motors or manage the coils of a single stepper motor.
• Ultra-Low Voltage Operation: Supports a wide motor supply voltage range from 2.7 V up to 10.8 V, making it ideal for 3V, 5V, or 9V battery applications.
• High Current Capacity: Delivers a continuous current of 1.5 A per channel, with transient peak currents reaching up to 2 A, supporting most small and medium DC motors.
• Built-in Protection: Features thermal shutdown, undervoltage lockout (UVLO), and overcurrent protection, safeguarding the driver IC and your motors.
• PWM Control: Easily adjust the motor speed using standard Pulse Width Modulation (PWM) signals from any microcontroller.
• Small Form Factor: The compact breakout board design integrates cleanly into small chassis and dense electronic layouts.
