Garmin LIDAR-Lite v4 LED - Distance Measurement Sensor

The LIDAR-Lite v4 LED is the next step in the LIDAR-Lite line from Garmin™. While the v3 focuses on raw distance, the LIDAR-Lite v4 LED prioritizes intelligence and efficiency. It is the first optical ranging sensor to incorporate ANT® wireless networking, making it the smartest, most adaptable sensor in its class.

Next-Generation Capabilities

The v4 LED redefines what a compact sensor can do! By combining a safe LED emitter with a powerful onboard processor, it offers a versatile platform that goes far beyond simple distance measurement:

• Smart & Wireless: The first optical sensor to feature built-in ANT® technology, allowing for wireless telemetry and communication with other ANT-enabled devices.
• Programmable Core: Powered by a Nordic nRF52840 processor. Developers can write custom applications to run directly on the sensor, effectively turning it into a standalone device.
• Eye-Safe & Efficient: This sensor ditches the laser and instead utilizes a focused 940nm LED emitter (Class 1), making it inherently safe for open environments while consuming only 85mA during acquisition.

Performance & Integration

Designed for short-range precision, the v4 LED delivers reliable readings from 5 cm up to 10 meters. It operates on a standard I²C interface but adds the flexibility of the ANT wireless protocol. Because it operates at a 3.3V logic level (with a 5V power input), it pairs well with modern microcontrollers. Its ultra-compact form factor makes it the ideal building block for robotics, IoT, and unmanned vehicles where size, weight, and power are critical.
