Product Description

The board uses two L293D chips. Each one has two H bridge that can controls two motors. 

 

 

 FAQ

Q:  How many motors can be connected at most?

A:   4 DC motors, or 2 stepper motors and 2 servo motors.

Following are options:

1. Connect 4 DC motors and 2 servos.

2. Connect 2 DC motors, 1 stepper motor and 2 servos.

3. Connect 2 steperp motors and 2 servos.

 

Q: Which ports are connected to DC/ Step motor?

A: DC / Stepper motors are not connected to Arduino directly. They are parallel-connected to 74HC595 and then controlled by Arduino. You cannot control the motor directly. You have to use motor driver board library to drive the motor.

 

Q: Which ports of Arduino are used by this driver board?

A: All of 6 analog ports are not used. They can also be used as digital ports(pins14-19).They normally are used to connect sensors.

    Digital ports 2 and 13 are not used.

   The following ports are used:

   Digital port 11: DC motor #1 / stepper #1(PWM)

   Digital port3: DC motor #2 / stepper#1(PWM)

   Digital port5: DC motor #3 / stepper #2(PWM)

   Digital port6: DC motor #4 / stepper #2(PWM)

   Digital port 4, 7, 8 and 12 are used when any DC motor or stepper motor is used.

 

Following ports will be used when driving servo motor:

 Digital port 9: servo control #1

   Digital port 10: servo motor#2

 

Q: How to connect unused ports?

A: Analog port (0-5 can be used as digital ports 14-19) is connected to headers at the low right corner. You can use them directly.

 

Common Issues

 

Q: I ran the example codes, and get the following error message:

“error: AFMotor.h: No such file or directory...."

A: Make sure you have installed the library AFMotor. Unzip the library file to the directory “libraries” of arduino.

Example: D:Program Filesarduino-0021libraries

And open Arduino IDE again. There are reference example codes available

.

Q: How to install into Arduino IDE

A: Install Arduino compatible with full-featured driver board library to

Arduino.  Unzip the library file to the directory “libraries” of Arduinio.

Example:D:Program Filesarduino-0021libraries

And open Arduino IDE again. There are reference example codes.
