L298N H-Bridge Dual Motor Driver, Stepper Motor Driver

L298N H-Bridge Dual Motor Driver Board is a high-power, heavy-duty motor controller module designed to drive DC motors and 4-wire stepper motors with ease. Built around the robust L298N dual H-bridge driver IC with internal heavy-gauge heatsinking, this module independently controls the direction and speed of two DC motors or one 2-phase stepper motor. Equipped with high-capacity filter capacitors, freewheeling protection diodes, an onboard 5V regulator, and heavy-duty screw terminal blocks, it is the premier choice for powering high-torque robotics, 2WD/4WD rovers, and high-current industrial actuators using microcontrollers like Arduino, ESP32, and Raspberry Pi.

Features

• Dual H-Bridge topology powered by the high-power ST L298N motor driver chip
• Capable of driving two DC motors independently (direction and PWM speed) or one 4-wire two-phase stepper motor
• High operating voltage range up to 35V DC with a continuous output current of 2A per channel (3A peak)
• Onboard 78M05 5V linear voltage regulator for supplying power to internal logic or external microcontroller boards
• Integrated thick aluminum heatsink providing effective thermal dissipation under heavy motor load conditions
• Heavy-duty screw terminal blocks for secure connection of motor wiring and external power supplies
• Freewheeling protection diodes guarding against inductive kickback voltage spikes from inductive motor coils
• Enable pins (ENA, ENB) allowing precise PWM speed control and rapid motor braking/coasting functionality

Applications

• 2WD, 4WD, and Mecanum wheel autonomous mobile robotics, rovers, and smart cars
• Heavy-duty high-torque DC motor control, linear actuator driving, and conveyor belts
• Stepper motor positioning systems, pan-tilt camera platforms, and automated valves
• RC vehicle modifications, motorized solar trackers, and automated door/gate systems
• Polytechnic diploma, university engineering thesis, and Arduino/ESP32 robotics projects

Important Notes:

• Onboard 5V Regulator Jumper (5V-EN):
• Jumper Inserted (Motor Voltage 7V to 12V): The onboard 78M05 regulator is enabled, generating a 5V logic supply. You can use the module's 5V terminal to power your Arduino/microcontroller.
• Jumper Removed (Motor Voltage > 12V): You must remove the jumper to prevent damaging the 5V regulator. In this state, connect an external 5V logic supply to the board's 5V terminal.

• PWM Speed Control: To control motor speed using PWM, remove the jumpers on the ENA (Channel A) and ENB (Channel B) pins and connect them to PWM-capable GPIO pins on your microcontroller.
• Common Ground Connection: Always ensure the ground (GND) of your external motor power supply is connected to the GND of your microcontroller board for stable signal switching.
• Heat Management: When operating continuously near the 2A limit, ensure adequate airflow or add active cooling to prevent thermal shutdown of the L298N chip.
