Benewake TF-LC02 Lidar Range Finder Sensor Ranging Module (VCSEL)

Ultrasonic distance sensors can struggle with soft or angled surfaces that scatter sound waves instead of reflecting them cleanly back, and that's exactly the weakness a lidar module like this one avoids by measuring a laser pulse's time of flight instead. Benewake's VCSEL-based TF-LC02 brings that laser-ranging accuracy to a small, low-power module that drops straight into an Arduino, Raspberry Pi, or STM32 project needing reliable short-range distance measurement.
