Driver L298N

Description of L298N Motor Driver
The L298N is a dual H-Bridge motor driver IC, designed to control the direction and speed of motors in various robotics and automation applications. It is widely used in projects requiring control of DC motors, stepper motors, or other inductive loads. The L298N can handle high current and voltage, making it suitable for driving larger motors. It allows for bidirectional control (forward and reverse) of motors and provides the option for speed control via PWM (Pulse Width Modulation).

This motor driver is capable of controlling two DC motors simultaneously or a single stepper motor, and it is capable of delivering up to 2A per motor with proper cooling. The L298N module includes protection features, such as diodes to protect against back EMF (Electromotive Force) generated by the motors. This makes it a popular choice for many robotics, automation, and DIY projects.
