Description:
L293D is a monolithic integrated, high voltage, high current, 4-channel driver.Basically this means using this chip you can use DC motors and power supplies of up to 36 Volts, thats some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what’s known as a type of H-Bridge. 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. motor.
Features:
● 2 interface for 5V Servo connected to the high-resolution dedicated timer - no jitter!
● Can drive 4 DC motors or 2 stepper motors or 2 Servo
● Up to 4 bi-directional DC motors with individual 8-bit speed selection
● Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
● 4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC
● Pull down resistors keep motors disabled during power-up
● reset button
● 2 external terminal power interface, for seperate logic/motor supplies
● Tested compatible for Mega, Diecimila & Duemilanove
Arduino is a good introduction to electronics, with motor extension board can good become robot development platform. Here one can drive all kinds of simple introduction to the slightly complex projects fully functional extension plate of motor.
This is a commonly used dc motor driver module, using 293 d small current dc motor driver chip. Pin have been made into the Arduino compatible, lovers also facilitates rapid development based on the Arduino.
* 2 5 v servo motor (steering) port connected to the Arduino high resolution and high precision timer - no shaking!
* and 4 road up to four two-way dc motor PWM speed resolution (about 0.5%)
* up to 2 stepper motor control, operations control, single/double step interlaced or micro step and rotation Angle control.
* 4 H - bridge road, L293D chip per luqiao. 0.6 A peak 1.2 (A) current with thermal power protection, 4.5 V to 36 V.
* pulldown resistor to ensure in the electric motor to keep stop state.
* make it easier for wiring terminal terminal (10 to 22 awg) and power supply.
* with the Arduino reset button.
* two large terminal external power supply terminals Ensure the logic and motor driven power separation.
* compatible with UNO Mega, Diecimila, & Duemilanove.
* download convenient use Arduino software library for project development quickly
Scope of application: the Arduino beginner, Arduino experiment equipment platform, interactive electronic Arduino, Arduino robot, etc.
Characteristics: more functions, convenient operation, powerful drive library support and update.
Weakness: the I/O occupy more at the same time under the condition of four road motor (relative Arduino less I/O version), small power.
To drive dc motor or 2 road 4 step motor at the same time also can drive 2 road steering gear, support for the latest Arduino UNO, Arduino Mega 2560
You can match like this:
Four dc motor and two road steering gear drive
Driven by two dc motors and stepper motor and two lines of steering gear
Driven by two stepper motors and two road steering gear
