Mounting Options

Cable tie: You can secure the device to your application using a
3.6 mm (0.14 in.) wide cable tie. You should route the cable
tie through the channel in the center of the device.
Double-sided tape: You can secure the bottom of the device to
your application using double-sided tape. For best results,
you should select a tape that has a high-strength bond.
Labeling Requirements
The LIDAR-Lite v4 LED device is an FCC-certified transmitter. If
you are integrating the device with another product, you must
ensure the FCC ID is visible from the outside of your product.
You are responsible for meeting any other labeling requirements
imposed by the FCC rules and any rules related to the
compliance of your end product.
Connections
LIDAR-Lite v4 LED Connection Diagram
The through-holes on the LIDAR-Lite v4 LED device are
arranged in 2 rows of 5 holes each, with a 2 mm pitch between
each connection.
The LIDAR-Lite v4 LED maximum signal level is 3.3 V. A signal
greater than 3.3 V will damage the device.
