What is IBT-2 module?
The IBT-2 module is a type of dual-channel motor driver commonly used in robotics and electronics projects. It’s designed to control two DC motors bidirectional, allowing them to move forward, backward, or brake. This module can handle moderate currents and voltages, making it suitable for various applications where motor control is required, such as in small robots, RC vehicles, and other electromechanical systems. Its features often include PWM speed control, over current protection, and a straightforward interface for connecting to microcontrollers or other control systems.
How IBT-2 Works?
The IBT2 is a dual-channel H-bridge that can control the speed and direction of a DC motor.
Controlling motor speed using an IBT2 H-bridge motor driver and an Arduino is a common and straightforward project.

IBT-2 motor Driver Pin out:
The IBT-2 motor driver is a popular dual-channel H-bridge motor driver often used to control DC motors or stepper motors.
Its Pinout typically includes the following:
IN1, IN2:
These pins control the direction of the first motor. By applying different logic levels (HIGH or LOW) to these pins, you control the motor’s rotation direction.
IN3, IN4:
Similar to IN1 and IN2, these pins control the direction of the second motor (if you’re using both channels).
ENR, ENL:
These pins are used to enable or disable the motor driver. Applying a PWM signal to these pins allows you to control the motor’s speed.
OUT1, OUT2:
Output terminals for the first motor. The motor connections are made here.
OUT3, OUT4:
Output terminals for the Power Supply.
