The Benewake TFS20-L Miniature Single-Point LiDAR Distance Sensor provides real-time digital rangefinder telemetry using direct Time-of-Flight (dToF) laser pulses, giving your flight controller exact ground-truth altitude hold without the drift. With our 10 years of experience in the manufacturing and delivery of commercial FPV systems across the UK, we know that optical distance sensing beats firmware guessing every single flight. Whether wired to an open UART on ArduPilot or routed through I2C on custom robotics, this micro sensor delivers rock-solid terrain following without the magic smoke.\u003c\/p\u003e\n\n\u003ch3\u003eKey Highlights\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect Time-of-Flight Ranging:\u003c\/strong\u003e Uses a high-sensitivity SPAD sensor and fast TDC architecture for precise optical distance telemetry up to 20 metres.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeatherweight Footprint:\u003c\/strong\u003e Tipping the scales at just 1.35g, it mounts effortlessly inside tight drone frames, micro-gimbals, and autonomous rovers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBroad Protocol Support:\u003c\/strong\u003e Supports both UART and I2C interfaces for rapid serial telemetry integration with popular autopilots and microcontrollers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy You Want a Single-Point LiDAR Distance Sensor\u003c\/h3\u003e\n\u003cp\u003eBecause barometric pressure fluctuates with every gust of wind and ultrasonic sensors get deafened by prop wash.
