L293D Dual H-Bridge Motor Driver Module

The L293D Motor Driver Module is a compact dual H-bridge motor-control board designed to interface DC motors and bipolar stepper motors with microcontrollers such as Arduino. It allows low-current digital control signals from a microcontroller to operate motors requiring a separate power supply.

Based on the L293D motor driver IC, the module provides two independent H-bridge channels, allowing two DC motors to be controlled independently for forward and reverse operation. It can also be used to control a suitable bipolar stepper motor.

The module provides separate motor power and logic connections, along with enable and input pins for controlling motor operation. The enable inputs can also be controlled using PWM for basic motor-speed control.

Built-in protection diodes help protect the driver circuitry from voltage spikes produced by inductive motor loads. The module is suitable for small robotics platforms, Arduino projects, educational electronics, automation and other low-power motor-control applications.
