Custom 1pcs L293D Motor Drive Shield dual for arduino Duemilanove Motor drive expansion board motor control shield

It is a good introduction to electronic production. With the motor expansion board, it can be a good platform for robot development. Here is a fully functional motor expansion board that can drive a variety of simple to slightly more complex items.

This is a commonly used DC motor driver module, using 293D chip small current DC motor driver chip. Pins are made to be compatible and to facilitate rapid based development by hobbyists.

* 2 5V servo motor (steering gear) ports connected to Arduin high resolution and high precision timer - no jitter!

* Up to 4 bidirectional DC motors and 4 channels PWM speed control (about 0.5% resolution)

* Up to 2 stepper motors for forward and reverse control, single/double step control, staggered or micro-step and rotation Angle control.

* 4-channel H-bridge: L293D chip provides 0.6A (peak 1.2A) current per bridge with thermal power off protection, 4.5V to 36V.

* The pull-down resistor ensures that the motor stays stopped when it is powered on.

* Large terminal terminals make wiring easier (10-22 AWG) and power.

* With Arduino reset button.

* 2 large terminal external power terminals ensure separation of logic and motor drive power.

* Compatible with Mega, Diecimila, & Duemilanove.

* Download the easy-to-use Arduino software library for quick project development

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

Features: Many functions, easy to operate, a powerful driver library support and functional update.

Disadvantages: High I/O occupancy, low power when driving four motors at the same time (compared to the version with less Arduin I/O).

It can drive 4-way DC motor or 2-way stepper motor at the same time it can drive 2-way steering gear, supporting the latest Arduin UNO, Arduin Mega 2560

You can match it like this:

Drive four - way dc motor and two - way steering gear

Drive two DC motor and one step motor and two steering gear

Drive two stepper motor and two steering gear
