Custom L293D motor control shield motor drive expansion board FOR Arduino motor shield

Data download link: http://pan.baidu.com/s/1vKW8V

Scope of application: rduino beginners, rduino experimental equipment platform, rduino interactive electronics, Arduino robot, etc.

Features: many functions, easy to operate, has a powerful driver library support and function update.

Disadvantages: I/O usage is higher in the case of driving four-way motors at the same time (compared to the rduino I/O less version), low power.

It can drive a 4-way DC motor or a 2-way stepper motor while also driving a 2-way steering gear, supporting the latest rduino UNO, rduino Mega 2560

You can match them like this:
Drive four-way DC motor and two-way steering gear
Drive two direct current motor and one step motor and two steering gear
Drive two-way stepper motor and two-way steering gear

rduino is a good introduction to electronics manufacturing, and with the motor expansion board can be a good platform for robot development. Here we introduce a fully functional motor expansion board that can drive a variety of simple to slightly complex projects.
This is a commonly used DC motor drive module, using 293D chip small current DC motor drive chip. The pins are made RDUino-compatible and also facilitate fast Rduino-based development by enthusiasts.

* 2 5V servo motor (steering gear) ports connected to the Arduino's high resolution high precision timer - no jitter!
* Up to 4 bi-directional DC motors and 4 PWM speed controls (approx. 0.5% resolution)
* Up to 2 stepper motor forward and reverse control, single/double step control, staggered or micro-step and rotation Angle control.
* 4-way H-bridge: The L293D chip provides.0.6A (peak 1.2A) current per bridge with thermal outage protection, 4.5V to 36V.
* The pull-down resistor ensures that the motor stays stopped when powered on.
* Large terminal terminals make wiring easier (10-22 AWG) and power supply.
* With Arduino reset button.
* 2 large terminal external power terminals ensure separation of logic and motor drive power.
* Compatible with Mega, Diecimila, & Duemilanove.
* A full set of spare parts is available for enthusiasts who want to do it themselves.
* Download easy to use Arduino software library for quick project development
