1) Arduino / Genuino is Arduino AG are registered trademarks.
2) Stress exceeding this voltage or current may risk damage to the device. Functionality and reliability may be hindered if the device exceeds
these values. The maximum current value, IOmax, does not guarantee the module can handle that much current. If the device
overheats, thermal shutdown will occur.
3) Contents of kit may not be compatible with different versions. Please see the Appendix attached if specified version is not installed.

②Include the API Library
As shown below, navigate to Sketch→Include
Library→Add .Zip Library
The following window will appear. Select the
“LV8548_DC_APILibrary” folder, and open this
folder as shown below.
Click the folder only once and push “Open” button.
Do not double click the folder.
Unless updating the function library, including the
API function library only needs to be done once.
Writing and Compiling with the Arduino IDE
①Select the Arduino board to upload to by
navigating to
“Tools→Board→Arduino/Genuino Micro”
②Write an Arduino sketch and navigate to
“Sketch→Verify/Compile” when finished
writing
The IDE will display “Done compiling” after a
successful compile has been verified.
③Connect the PC to the Arduino Micro via
USB and select the corresponding COM port
④Upload the sketch byclicking “Sketch→Upload”
or by pressing the ○ →button
The IDE will display “Done uploading” after a
successful upload to the Arduino
Sketches written to the Arduino will not be erased
unless rewritten.

If the uploading of the program fails confirm the
details in step ①check board name and step ③
check serial port connection.
Rewrite the Arduino Program
In the case of ①or ②below, please rewrite the
program to the Arduino
①When updating the API Function library
1)Delete the existing API function library by
navigating to Documents\Arduino\libraries
and deleting the LV8548_DC_APILibrary
folder.
2)Include the latest API function library.
Please save the latest API function library
in your preferred directory on your PC.
(See Page 2, “Software Setup”)
Include the latest API function library.
(See Page 2 “API Library”)
3) Compile and write the program to the
Arduino
(See Page 3, “Writing and Compiling with
the Arduino IDE”)
②Whenevaluating the LV8548 Stepper and other
motor driver modules
(Assuming other motor driver module libraries
have already been included)
1) Compile and write the program to the
Arduino
(See Page 3, “Writing and Compiling with
the Arduino IDE”)
If you are testing the LV8548 Stepper module
library or any other motor driver module library
for the first time, please operate according to
their corresponding manual.
GUI Installation
①In the folder, double
click and run installation file.
*If a previous version of ON_MD_Module_Kit_GUI
has already been installed, please uninstall and
reinstall the GUI
②If .NET Framework4.6.1 is not installed, click
Accept to install.
The following window shows the installation in
progress. (This may take several minutes)
If the installation requires a reboot to complete, a
message will appear on the screen. Please press
“Yes” to reboot.

Hardware Setup
①Connect the LV8548MCSLDGEVB（Motor Driver Module）to the ONBB4AMGEVB（Motor Driver
Baseboard）. Insert the module into the baseboard, while being careful not to bend the header pins
②Connect the Arduino/Genuino Micro to the baseboard, as seen in the figure below. The USB connection
port should be labeled on the baseboard ”USB” to dictate the orientation of the Arduino
③Plug in the motor wires (Insulation between 5mm –10mm) into the output terminals on the baseboard –
OUT_A/B/C/D. Refer to the table below for motor connectivity:
OUT_A
Motor1＋
OUT_B
Motor1－
OUT_C
Motor2＋
OUT_D
Motor2－
（Double check the motor wires, + and -, to ensure correct rotation direction）
④Connect the Arduino to a PC using a USB cable.
⑤Insert the AC Power adapter into the DC Jack on the baseboard. Be sure that a Center positive type
adapter is being used with an output voltage of 4-16V.
If using power supply cables, please connect the positive terminal to VCC and the negative terminal to
GND in the CN6 connector. The power supply terminals +/- at CN6 are polarity sensitive.(VCC=+,
GND=-)

①Double-click the GUI shortcut and connect the
COM serial port.
Available COM ports will appear in the drop-down
box.
If the Arduino is connected correctly to the PC, an
option for “Arduino Micro (COMx)” will be available
(where x is the number associated with the port);
select that COM port and click “Connect”.
②The GUI will automatically navigate to the
LV8548DC tab after the Arduino installed the
firmware is connected.
③Specify the desired frequency for PWM
④Set the PWM mode for each motor (Ch1 &
Ch2)
If the motor is running, it is recommended to
press the “Brake” or “Open” button before
switching the direction of rotation.
Please see the Appendix for characteristics
regarding the PWM frequency and PWM
mode.
⑤Change the On Duty ratio for each motor
(10-20% is recommended)
⑥Press the “Start” button to begin motor function

Adjusting the duty ratio while the motors are
rotating is recommended
Be sure to adjust the duty ratio gradually. For
safety reasons, please initiate the motors at a
lower duty ratio and increase gradually.
The Brake function sets the potential at both
leads of the motor to ground and instantly
stops the motor.
The Open function sets both leads of the motor
to an open circuit, which decelerates the motor
to a complete stop.
For additional details, please see the attached
Appendix.
For more details on the following features, please
refer to the attached Appendix:
⑦GUI Language configuration
⑧GUI Tool Tip display
⑨Help function
⑩Closing the GUI
When finished, exit the GUI by pressing the “Exit”
button at the bottom right of the screen or by
clicking “Exit” item at the top menu bar.
The following popup message will be displayed
when exiting the GUI.
Select “Yes” to quit the GUI.
Select “No” to cancel the exit and return to the main
screen.
If the GUI is closed while the motor is still running,
the motor will be stopped and the window will
close.

By pressing the “SAVE” button, the content displayed on the work log can be saved as a .txt file or a .csv
file.
⑫Clear GUI Log
By pressing the “CLEAR” button, the content displayed on the work log will be erased.
⑬Program Generation
Pressing the “Generate Program” will output the executed API functions on the work log into a .ino
program file that can be uploaded directly with Arduino. By writing the output of the .ino file to Arduino,
motor control can be executed automatically through standalone operation according to the procedure
generated through the GUI Log.
