L293D Motor Shield for Arduino

L293D Motor Shield for Arduino

The L293D Motor Shield is a popular motor driver shield designed for controlling motors with Arduino and other microcontroller platforms. It can drive DC motors, stepper motors, and even relays. Below are the key features:

Key Features:

Dual H-Bridge Motor Driver: The shield has two L293D ICs, which allow it to control up to 4 DC motors or 2 stepper motors simultaneously. Each motor can be independently controlled in both directions.

Current Limit: Each L293D can deliver up to 600mA of continuous current per channel, with peak currents of 1.2A per channel.

Voltage Support: The shield can control motors with voltages ranging from 4.5V to 36V, making it versatile for different motor types.

PWM Speed Control: Built-in Pulse Width Modulation (PWM) support allows precise speed control for motors.

Stackable Design: It fits directly onto Arduino boards and is stackable, so additional shields can be added for more functionality.

Servo Motor Control: The shield also includes connectors for up to 2 servos, which can be controlled via Arduino’s PWM pins.

Built-in Protection: The L293D ICs offer thermal shutdown and internal diodes for protection from back EMF.

Applications:

• Robotics projects requiring motor control
• Automated systems and vehicles
• DIY projects with multiple motors
• Stepper motor-based projects like CNC machines
