L293d Motor Driver Shield Circuit Diagram

These ics are designed to control 2 dc motors simultaneously.

L293d motor driver shield circuit diagram.

Drives come in many different types. 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. Circuit diagram for l293d motor driver ic controller. Vcc is the voltage that it needs for its own internal operation 5v.

In this instruction you learn to work on the l293d motor shield. A motor driver is an integrated circuit chip which is usually used to control motors in autonomous robots. The h bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output e g. L293d will not use this voltage for driving the motor.

For driving the motors it has a separate provision to provide motor supply vss v supply. Wiring l293d uno mega shield with stepper motor the l293d is a dedicated module to fit in arduino uno r3 board and arduino mega it is actually a motor driver shield that has full featured arduino shield can be used to drive 2 to 6 dc motor and 4 wire stepper motor and it has 2 set of pins to drive a servo. 2 connections for 5v hobby servos connected to the arduino s high resolution dedicated timer no jitter. The l293d is quadruple high current half h drivers it is designed to provide bidirectional drive currents of up to 600 ma at voltages from 4 5 v to 36 v.

Download the l293d schematic in as eagle project. The l293d belongs to a sort of h bridge motor driver shield quadruple high current half h driver used to provide bidirectional drive currents of up to 600 ma at voltages from 4 5 v to 36 v. Drivers are enabled in pairs with drivers 1 and 2 enabled by 1 2en and drivers 3 and 4 enabled by 3 4en. The l293d is a dedicated module to fit in arduino uno r3 board and arduino mega it is actually a motor driver shield that has full featured arduino shield can be used to drive 2 to 6 dc motor and 4 wire stepper motor and it has 2 set of pins to drive a servo.

The most commonly used motor driver ic s are from the l293 series such as l293d l293ne etc. Motor driver act as an interface between arduino and the motors. L293d shield is a driver board based on l293 ic which can drive 4 dc motors and 2 stepper or servo motors at the same time. Other important l293d features are.

The schematic diagram is as follows. Each output is a complete totem pole drive circuit with a darlington transistor sink and a pseudo darlington source. Here is a design for a full featured motor shield that will be able to power many simple to medium complexity projects.
