L293D Motor Driver Module for Arduino

The L293D is a smaller-scale alternative to boards like the L298N - built around the same dual H-bridge concept but sized for lighter loads, with a 600mA continuous rating per channel (1.2A peak, non-repetitive) rather than several amps. That makes it a better fit for small hobby motors and light robotics builds where a heavier-duty driver would be unnecessary bulk and cost.

Four direction control inputs and two speed control (PWM) inputs give independent control over both connected motors, and the module includes overtemperature protection along with an enable facility that lets a project cut motor power in software without physically disconnecting anything. Running on a 5V to 12V supply keeps it compatible with the same battery packs already powering an Arduino-based robot.

Common uses are small line-following and obstacle-avoiding robot kits, light two-motor chassis projects, and beginner robotics builds where the driver just needs to reliably switch and reverse two small DC motors.
