Scope of application: Arduino-beginners, [Arduino] experimental equipment platform, [Arduino] interactive electronics, Arduino-robots, etc.

Characteristics: Multi functional, easy to operate, with powerful driver library support and function updates.

Disadvantages: High I/O usage and low power consumption when driving four motors simultaneously (compared to Arduino-versions with fewer I/Os).

It can drive 4-way DC motor or 2-way stepper motor, and also drive 2-way steering gear, supporting the new Arduino-UNO, Arduino-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


[Arduino] is a good introduction to electronic production, and with the motor expansion board, it 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 Arduino-compatible, which also makes it easy for enthusiasts to quickly develop Arduino-based items.


* 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 reversed 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
