15A Single DC Motor Driver

The DFRobot DRI0042 is a compact, high-current DC motor driver capable of continuously driving a single motor at up to 15A (with heatsink) from a 12–36V supply. The onboard LM2575 regulator provides a 5V 500mA output for powering an Arduino or other controller, and all control signal inputs include ESD protection.

Direction is controlled via IN1/IN2 logic pins (3.3V/5V compatible) and speed is regulated using a PWM input. The board features under-voltage lockout (UVLO) protection to safeguard your system, and uses pluggable screw terminals for easy wiring.

Key Features

• High Current Output – 12A continuous (no heatsink), 15A (with heatsink), 20A (with active cooling); 110A peak
• Wide Voltage Range – 12–36V supply (6.5–40V absolute limit)
• 3.3V/5V Logic Compatible – Works directly with Arduino, Raspberry Pi, and other microcontrollers
• 5V Regulated Output – 500mA output to power your controller from the motor supply
• Full Protection – UVLO (under-voltage lockout) and ESD-protected control inputs
• Compact Size – 55 × 55 × 20 mm
