The Garmin LIDAR-Lite V4 LED is a compact, low-power optical distance sensor that measures up to 10 metres using lensed LED light (not a laser, despite the name). Drawing only 85 mA during acquisition with measurement rates up to 200 Hz, it's an ideal alternative to ultrasonic sensors for robotics, IoT, and unmanned vehicles.

Connect via I²C to read distance values from any microcontroller, or use Garmin's ANT wireless protocol for cable-free operation. The built-in nRF52840 processor runs a preloaded stock application out of the box, or experienced developers can create custom firmware and push over-the-air updates via Bluetooth LE.
