DUE I2C Wiring
NOTICE
The LIDAR-Lite v4 LED maximum signal level is 3.3 V. A signal
greater than 3.3 V will damage the device.
You should connect the Arduino DUE and the LIDAR-Lite v4
LED as shown in the diagram and table.
NOTE:
You must splice the ground wires so all components
share a common ground. These components include the power
supply, the programmer, the microcontroller operating I2C, and
any GPIOs.

Troubleshooting
Product Support
Contact your authorized Garmin Reseller for troubleshooting
information related to your device and its specific application.
Go to
for general help and information,
such as product manuals, specifications, and frequently asked
questions.
The I2C is not responsive while the device is powered
on
GPIO B is used as a boot pin to start the LIDAR-Lite v4 LED
Bluetooth LE bootloader. If GPIO B is grounded when the device
is powered on, the bootloader is enabled and I2C and ANT
functionality are disabled.
Verify GPIO B is not grounded.
I cannot connect my device to the Garmin PC
simulator
• Ensure the ANT network key is configured correctly.
◦ If the LIDAR-Lite v4 LED device still has the default
application installed from the factory, verify that you have
the Garmin developer key selected.
◦ If you have reprogrammed the device and you are using
the public network key, verify that you have the public
network key selected.
• Verify that you have the same RF frequency selected on both
the LIDAR-Lite v4 LED device and the Garmin PC simulator.
• Verify that you have the correct channel parameters selected.
TIP:
You can set wildcards for the channel parameters to
connect to any device. On the PC simulator, if you set the
device number and transmission type to zero, the Garmin PC
simulator connects to a device with any device number and
transmission type.
Can I use a microcontroller with 5 V signaling?
The LIDAR-Lite v4 LED device is tolerant to only 3.3 V. If you
need to use a 5 V system, such as the Arduino Uno, you must
use a logic level converter to protect the I/O drivers in the
LIDAR-Lite v4 LED device. Garmin does not endorse or
recommend using a microcontroller with 5 V signaling.
