L293d Motor Driver Shield Circuit Diagram

The schematic diagram is as follows.

L293d motor driver shield circuit diagram.

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. 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. Here is a design for a full featured motor shield that will be able to power many simple to medium complexity projects. In this instruction you learn to work on the l293d motor shield.

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. Download the l293d schematic in as eagle project. For driving the motors it has a separate provision to provide motor supply vss v supply. Drivers are enabled in pairs with drivers 1 and 2 enabled by 1 2en and drivers 3 and 4 enabled by 3 4en.

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. Each output is a complete totem pole drive circuit with a darlington transistor sink and a pseudo darlington source. The driver is an interface circuit between the motor and controlling unit to facilitate driving. Drives come in many different types.

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. Vcc is the voltage that it needs for its own internal operation 5v. These ics are designed to control 2 dc motors simultaneously. 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.

The l293d ic is designed to drive inductive loads such as relays solenoids dc and bipolar stepping motors. Motor driver act as an interface between arduino and the motors. Other important l293d features are. A motor driver is an integrated circuit chip which is usually used to control motors in autonomous robots.

2 connections for 5v hobby servos connected to the arduino s high resolution dedicated timer no jitter. 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. L293 and l293d are characterized for operation from 0 c to 70 c.
