Garmin LIDAR-Lite v4 LED - Distance Measurement Sensor (Qwiic)

The Garmin LIDAR-Lite v4 Qwiic is an outstanding wireless optical distance measurement sensor. No soldering is needed to start using it, making it perfect for drones, robots, IoT, or unmanned vehicles when space and power are limited. It has a range of up to 10 meters and a 1cm resolution, consuming only 85mA during data acquisition. You can use the I2C protocol to read and write to it, and the SparkFun Qwiic system makes this even easier. It operates on 5V but uses 3V3 logic. With a 5V boost circuit and a user - friendly Qwiic connector, you can power the sensor and get distance measurements all with one piece of hardware. This sensor sends out an infrared beam and measures the reflection time. It uses LEDs instead of lasers, so it's eye - safe in normal use. The built - in nRF52840 microcontroller has a pre - loaded application to calculate distance and also allows developers to create custom apps. The SparkFun LIDAR Lite v4 Arduino library simplifies data collection. You can change the I2C address and daisy - chain up to 10 sensors on one platform. Note that the Qwiic LIDAR - Lite v4's I2C address is 0x62 and is software - configurable. A multiplexer is needed for multiple sensors. The SparkFun Qwiic Connect System speeds up prototyping and reduces errors. Features include a 1cm resolution, a 5cm - 10m range, and various interface options. It also has detailed documentation and related videos available.

Using the Garmin LIDAR - Lite v4 Qwiic is easy. First, connect it to your device using the Qwiic connector. No soldering is required, which saves you time and effort. To get distance measurements, you can use the SparkFun LIDAR Lite v4 Arduino library and call the getDistance() function. If you want to change the I2C address, the library also provides an example on how to do that. When using multiple sensors, you'll need a multiplexer. Make sure to operate it within the temperature range of - 20 to 60°C. Also, keep in mind that the power supply should be 3.3VDC. For maintenance, just keep it clean and away from extreme conditions. Check the documentation regularly for any updates or new features. With its eye - safe LEDs and pre - loaded application, you can start measuring distances right out of the box. And if you're a developer, feel free to create your own custom applications to expand its functionality.
