Description
The L293D Motor Driver Shield for Arduino is a robust, high-performance shield designed for building Arduino-based robotics and automation systems. Equipped with dual L293D H-Bridge motor drivers and a 74HC595 shift register, this shield can control 4 DC motors, 2 stepper motors, or 2 servo motors simultaneously with precise control.
-
Dual L293D Motor Driver Chips: Each supports up to 600mA per channel (1.2A peak) with thermal and kickback protection.
-
PWM Motor Speed Control: Integrated with Arduino’s PWM pins for smooth and adjustable motor speed control.
-
Servo Motor Support: Two dedicated 5V servo connectors powered via Arduino pins 9 and 10.
-
Multiple Motor Types: Controls DC motors, unipolar or bipolar stepper motors with various stepping modes (single, double, interleaved).
-
Power Flexibility: Supports motor voltages from 4.5V to 25V via external 2-pin terminal block.
-
Safe Operation: Built-in pull-down resistors keep motors disabled during startup for safe booting.
-
Shift Register Expansion: 74HC595 chip expands Arduino I/O, allowing control of 8 motor outputs with just 3 Arduino pins.
-
Easy Connectivity: Large terminal blocks support 18-26 AWG wires, making motor wiring simple and secure.
-
Board Compatibility: Fully compatible with Arduino UNO, Mega 1280/2560, Duemilanove, and Diecimila.
This shield is ideal for Arduino robotics kits, automated vehicles, robotic arms, and smart DIY projects requiring reliable multi-motor control.
