Summary of SPARKFUN GARMIN LIDAR-LITE V4 DISTANCE MEASUREMENT SENSOR
SparkFun Garmin LIDAR-Lite v4 Qwiic LED Distance Measurement Sensor is a high-performance, eye-safe optical range sensor with up to 10 m range, 1 cm resolution, and 85 mA acquisition current. It uses LEDs (not a laser), communicates over I2C via the Qwiic system, requires 5 V power while using 3V3 logic, and includes a preloaded nRF52840 microcontroller application for out-of-the-box distance readings; developers can also program the nRF52840 for custom behavior.
Parts used in the SparkFun Garmin LIDAR-Lite v4 Qwiic LED Distance Measurement Sensor:
- SparkFun Garmin LIDAR-Lite v4 Qwiic LED Distance Measurement Sensor module
- Qwiic connector (built-in on the module)
- nRF52840 microcontroller (built-in on the module)
- 5V power source
- 5V boost circuit (on-module or external to provide 5V)
- I2C communication interface (Qwiic/I2C wiring)
SparkFun Garmin LIDAR-Lite v4 Qwiic LED Distance Measurement Sensor is a high-performance, wireless optical distance measurement sensor that doesn’t require any soldering to get started. The LIDAR-Lite Sensor features up to a 10-meter range, 1cm resolution, and requires 85mA during data acquisition.
Using the I2C protocol, users can read and write to the LIDAR-Lite v4, utilizing the SparkFun Qwiic system. The LIDAR sensor requires 5V to operate but runs on 3V3 logic. With a 5V boost circuit and an easy-to-use Qwiic connector, users can power the sensor and get distance measurements over Qwiic, all with a single piece of hardware.
The SparkFun Garmin LIDAR-Lite v4 Qwiic LED Distance Measurement Sensor sends out an infrared beam and measures the time it takes to be reflected. The LIDAR-Lite v4 utilizes LEDs rather than a laser for this iteration and is inherently eye-safe under normal usage.
The built-in nRF52840 microcontroller runs a pre-loaded “out of the box” application to calculate the distance between itself and an object in front of it. The equipped nRF52840 also allows developers to create custom applications to expand on the “out of the box” functionality or connect to an external micro-controller running a custom user application.
