L293d Motor Driver Shield Schematic. Each channel of this module has the maximum current of 1 2a and doesn t work if the voltage is more than 25v or less than 4 5v. Vcc is the voltage that it needs for its own internal operation 5v.
This motor driver shield is based on l293d motor driver chip which is designed to provide bidirectional drive currents of up to 1 2 a each bridge with thermal shutdown protection at voltages from 4 5 v to 36v. The l293d motor driver ic is one of the cheap and easily available devices for controlling the speed and direction of rotation of dc and stepper motors. In this tutorial we demonstrate how to control various types of motors using the l293d motor driver shield.
It can control two dc motors.
This motor driver shield consists of an l293d motor driver ic a 6 pin switch to turn on off the power and an lm7805 voltage regulator to get regulated 5v. In this tutorial i will show you how to use this motor driver with arduino in controlling a simple dc motor and a 28byj 48 unipolar stepper motor. This is the official adafruit schematic drawing of the motor shield. Download the l293d schematic in as eagle project.
