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 Specifications Operating Voltage: 5V (logic), 4.5V-36V (motor) Max Motor Current: 600mA per channel (1.2A peak) Control: Up to 4 DC motors / 2 stepper motors PWM Speed Control: 4 channels Servo Support: 2 servo motor connections Protection: Thermal shutdown, back EMF diodes Dimensions: 69mm x 53mm (Arduino shield size) Pin Usage: D3, D5, D6, D11 for PWM; D4, D7, D8, D12 for directions
