If a jumper is present on this pin, so the pin connected to +5 V and the motor will be enabled, then the Motor B rotates maximum speed. If we connect this pin to Ground the Motor A will be disabled.ĮNB pin is used to control the speed of Motor B. In that way, we can control the speed of Motor A. If we remove the jumper, we need to connect this pin to a PWM input of the microcontroller. If a jumper is present on this pin, so the pin connected to +5 V and the motor will be enabled, then the Motor A rotates maximum speed. If both the inputs are either HIGH or LOW the Motor A will stop.ĮNA pin is used to control the speed of Motor A. When one of them is HIGH and the other is LOW, Motor A will start rotating in a particular direction.

These are used to control the rotating direction of Motor A. If both the inputs are either HIGH or LOW the Motor A will stop. If the 5V-EN jumper is removed, you need to connect it to the 5V power supply of the microcontroller. If the 5V-EN jumper is in place, this pin acts as output and can be used to power up a microcontroller or other circuitry (sensor). +5V pin supplies power for the switching logic circuitry inside the L298N IC. It needs to be connected to the power supply ground(negative). VCC pin is used to supply power to the motor. L298N Motor Driver Module Pin Diagram/Pinout/Pin configuration This IC has two enable inputs, these are provided to enable or disable the device independently of the input signals. According to the L298 datasheet, its operating voltage is +5 to +46V, and the maximum current allowed to draw through each output 3A. It accepts standard TTL logic levels (Control Logic) and controls inductive loads such as relays, solenoids, DC and Stepper motors. L298 is a high voltage, high current dual full-bridge motor driver IC. L298N Motor Driver Module Hardware Overview L298 motor driver IC This motor driver module consists of two main key components, these are L298 motor driver IC and a 78M05 5V regulator.

These modules can control two DC motor or one stepper motor at the same time. These are PWM – For controlling the speed and H-Bridge – For controlling rotation direction. This module uses two techniques for the control speed and rotation direction of the DC motors. This module consists of an L298 dual-channel H-Bridge motor driver IC. It can control both the speed and rotation direction of two DC motors. L298N module is a high voltage, high current dual full-bridge motor driver module for controlling DC motor and stepper motor.
