L293D Dual Channel DC Motor Driver Module
The L293D Dual Channel DC Motor Driver Module is a powerful and reliable solution for controlling the speed and direction of DC motors in robotics and automation projects. Built around the L293D motor driver IC, this module can independently drive two DC motors or one stepper motor, making it an essential component for DIY robotics, Arduino projects, and electronic automation systems. Its compact design, ease of use, and ability to handle medium-power motors make it a favorite among students, hobbyists, and professionals.
How It Works
The module works by receiving control signals from a microcontroller (such as Arduino, ESP32, or Raspberry Pi) and translating them into higher current and voltage levels suitable for driving motors. With support for forward, reverse, stop, and speed control via PWM (Pulse Width Modulation), the L293D makes motor control straightforward and flexible. The built-in diodes provide protection against back EMF, ensuring long-lasting and safe operation.
