L298N High-Current Motor Driver Module – Dual Channel H-Bridge for Robotics & DIY

Description

Product Overview

The L298N High-Current Motor Driver Module is a robust and reliable dual-channel H-Bridge driver, designed to act as a powerful interface between your low-voltage microcontroller and high-power motors. Built around the industry-standard ST L298N integrated circuit, this board allows you to independently control the speed and direction of two DC motors, or drive one bipolar stepper motor with precision.

Ideal for robotics, mechatronics projects, and industrial automation, this module simplifies motor control. By accepting standard TTL logic signals (5V) from controllers like Arduino, Raspberry Pi, STM32, or ESP32, it handles the high current requirements of your motors safely. The module includes built-in protection diodes and an optional 5V regulator, making it a complete and user-friendly solution for driving loads up to 35V and 2A.

Key Features

• Dual H-Bridge Design: Based on the ST L298N chip, featuring two independent H-bridges. Perfect for controlling two DC motors simultaneously (differential drive for robots) or one bipolar stepper motor.

• High Voltage & Current Handling: Operates with motor supply voltages from 5V to 35V and delivers a continuous 2A current per channel, with peaks up to 3A. Suitable for a wide range of 5V, 12V, and 24V motors.

• PWM Speed Control: Dedicated Enable pins (ENA & ENB) allow for precise speed regulation via Pulse Width Modulation (PWM) from your microcontroller, enabling smooth acceleration and deceleration curves.

• Onboard 5V Regulator: Features a built-in 78M05 voltage regulator. When the jumper is active, it can provide 5V power for the logic side directly from the motor supply (provided the supply is between 7V and 35V).

• Integrated Protection: Includes flyback (snubber) diodes for each output, protecting the IC from voltage spikes generated by motor inductance during operation.

• Clear Status LEDs: Onboard LEDs indicate power presence and motor direction activity, making troubleshooting and operation monitoring simple.

• Easy-Terminal Connections: Heavy-duty screw terminals provide secure, reliable connections for power supplies and motor wires, ensuring stability even in high-vibration environments.

• Standard Logic Interface: Control inputs are TTL-compatible (5V), allowing for direct connection to most microcontrollers without additional level shifting.
