Sparkfun原裝 Garmin LIDAR-Lite v4 LED - Distance Measurement Sensor、Arduino 雷射測距模組 (SPX-15776 更新 SEN-15776)
〔Product includes〕清單：
- 1x LIDAR-Lite v4 LED Sensor
- 1x Documentation
〔Product Overview〕
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.
