Overview

The PS2X&Motor Driver Board driver can drive 4 DC motors, 2 encoder motors, 2 stepper motors, 6

servos (two external power supplies), and drive current up to 2A. The driver board is specially designed for

the Arduino uno R3 motherboard. It can be directly plugged into the Arduino Uno.The motherboard

integrates a passive buzzer, 2 RGB LED lights, and 1 infrared receiver.

It also reserves for PS2 socket, Uart interface, I2C interface, ultrasonic obstacle avoidance module

socket and other sensor interfaces which is very convenient to externally connect various sensor modules.

Common problems

Q：How to power the PS2X&Motor Driver Board?

A：It can be directly powered by the DC port of Arduino UNO. The voltage range is 6~12V and the

current is 500mA~2A. Or PH2.0 wiring port power supply, the voltage range is 6~12V, there is a power

supply jumper cap on the drive board, you need to short circuit the IN and 5V.

Q：How many motors does the PS2X&Motor Driver Board can drive？

A：The PS2X&Motor Driver Board can drive 4 DC motors ,2 stepper motors or 2 encoder motors.

Q：How does PS2X&Motor Driver Board connect power drive servo？

A：PS2X&Motor Driver Board has D5, D6 two interfaces for external power drive servo.

The switch needs to be toggled to OFF, and the jumper cap is connected to 5V, EX. The external power

supply is connected to the PH2.0-2pin terminal, and Vin is the positive pole.

Q：I want to upload the sample program to the Arduino board, suggesting that the upload failed.

What is the reason?

A：Before uploading the sample program to the Arduino board, you need to check if the board and

the computer are properly connected, then install the driver and try again.

Q：I want to upload the sample program to the Arduino board, and then the motor does not work

after turning on the power. What is the reason?

A：Firstly, check if the green indicator on the Arduino UNO board is on. If it is not on, it means the

power supply is not normal. Check whether the battery voltage is above 6v. Then check whether the motor's

wiring port is consistent with the port set in the program. Turn it on again.

Q：How to install graphical programming library?

A：Download the relevant tutorial under this link: https://github.com/keywish/motor-drive-board

Q：Where can we download the program examples?

A：Download the relevant tutorial under this link: https://github.com/keywish/motor-drive-board

Q：My Arduino will crash when the motor is running. Is the drive broken?

A：When the motor is running, the power consumption is large. You need to ensure that the battery

has sufficient power. You can try to charge the battery before turning it on.

Software Installation

Install IDE software

Unzip the Arduino software installation package (path: MotorDriverBoard\ArduinoIDE) under the

MotorDriverBoard folder, or download it from the Arduino website, download the address :

https://www.arduino.cc/en/Main/OldSoftwareReleases#previous

Figure 4-1 Arduino IDESoftware installation package

Unzip the zip file and double-click the arduino.exe installation file to install it. Because the installation

of “arduino.exe” is very simple, it will not be explained here. It is recommended to quit the anti-virus

software during the installation process, otherwise it may affect the IDE installation. After the installation is

complete, click "arduino.exe" again to enter the IDE programming interface.

After the IDE installation, we connect the Arduino motherboard, right click on "My Computer"→

“Properties”→“Device Manager”→View“Port（COM 和LT）”.If you see the interface below, the

driver has the installation is successful. At this time, we open the IDE and select the corresponding

development board model and port in the toolbar to use it normally.

Figure 4-2 Driver installation successful interface

Notice:

1）If you connect the controller board to your computer, the computer does not respond. Right click on "My

Computer" and select Open Device Manager to view the port (com&lpt). If there is no com or lpt, or if there

is only an unknown device, there is a problem with the controller board or USB cable.

2）Right click on "My Computer" and select Device Manager to view the ports (COM and LPT). If there is

a yellow Arduino UNO exclamation point, this means you need to install the driver yourself, the drive path:

MotorDriverBoard\ArduinoIDE.

3）If the driver is always installed but eventually fail. Please uninstall the driver and reinstall >

automatically install the driver > restart the computer.

Install driver

1、If your computer is a Windows 7 system:

1）Firstly, right click on "My Computer" and open the Device Manager to view the ports (COM and LPT).

At this point you will see a "USB Serial Port", right click on "USB Serial Port" and select the "Update

Driver Software" option.
