Description

The L293D Motor Driver IC is a popular integrated circuit used in robotics and automation projects to control DC motors and stepper motors. It features dual H-Bridge circuits that enable bidirectional motor control with PWM support for speed regulation. Ideal for Arduino, ESP32, and other microcontroller projects, it can drive motors with voltages from 4.5V to 36V and up to 600mA per channel. With internal diodes for back EMF protection, it is safe and reliable for hobbyist and educational robotics projects.
