L293D Motor Driver IC

The L293D Motor Driver IC is a widely used dual H-bridge motor driver designed to control DC motors and stepper motors with ease. It allows low-current microcontrollers like Arduino, ESP32, ESP8266, and Raspberry Pi to control higher-current motors by acting as an interface between the control circuit and the motor power supply.

With built-in flyback diodes for protection and the ability to drive two DC motors independently (or one stepper motor), the L293D is ideal for robotics, automation, and embedded system projects.
