L293D Motor DriverServo Shield for Arduino

The L293D Motor Driver and Servo Shield for Arduino is a versatile expansion board featuring 2 servo connectors and 4 motor connectors for DC or stepper motors, making it ideal for robotic projects.

This Arduino compatible motor driver shield can drive 4 DC motors or two 4-wire stepper motors along with two 5V servos. It uses the L293D driver chips for DC motors and steppers, while servos are controlled through Arduino pin 9 and pin 10.

The shield includes two L293D motor drivers and one 74HC595 shift register. The shift register expands 3 Arduino pins into 8 control pins for managing motor directions. The output enable pins of the L293D are tied directly to Arduino PWM outputs.

Features:

• 2 connections for 5V hobby servos using Arduino’s high resolution dedicated timer
• 4 H-bridges using L293D chipset providing 0.6A per bridge (1.2A peak) with thermal shutdown and kickback protection diodes
• Supports motor voltage from 4.5VDC to 25VDC
• Drives up to 4 bidirectional DC motors with individual 8-bit speed control
• Supports up to 2 stepper motors (unipolar or bipolar) with single, double, or interleaved stepping
• Pull-down resistors keep motors disabled during power-up
• Large terminal blocks for easy wire connections (18 to 26 AWG)
• Arduino reset button extended to the shield
• 2-pin terminal block and jumper for external power and separate logic or motor supply
• Compatible with Arduino Mega 1280, Mega 2560, Diecimila, Duemilanove, and UNO
• Ready-to-use Arduino software library with examples available

Package Includes:

• 1 x L293D Motor Driver or Servo Shield for Arduino
