Benewake TF-LC02 ToF LiDAR Distance Sensor

Stop gluing clunky ultrasonic transducers to micro builds and hoping acoustic waves bounce off carpet. The Benewake TF-LC02 is a compact micro LiDAR distance sensor engineered for millimeter-precise Time-of-Flight rangefinding over serial UART without frying your flight controller stack or releasing magic smoke. Drawing on our 10 years of experience in the manufacturing and delivery of commercial FPV systems across the UK, we know that reliable obstacle detection and low-altitude hold demand optical accuracy rather than blind firmware guesswork. Powered by integrated TDC architecture, this tiny module feeds ground-truth telemetry directly to your microcontroller without cluttering your build.

Key Highlights

• Time-of-Flight Precision: Advanced Time-to-Digital Converter (TDC) architecture delivers rapid, millimeter-level optical ranging.
• Ultra-Compact Footprint: Measuring just 20mm × 11.5mm × 7.6mm, it fits neatly inside cramped micro drone frames and tight robotics hulls.
• Serial UART Interface: Plug-and-play TTL UART communication enables direct integration with popular microcontrollers and flight control hardware.

Why You Want the Benewake TF-LC02 ToF Sensor

Sonar modules are bulky, noisy, and consistently fail against acoustic-absorbing surfaces like grass or carpet. The Benewake TF-LC02 delivers true optical laser ranging in a form factor barely larger than a postage stamp. Its tight 9° field of view ignores off-axis clutter, feeding precise distance telemetry from 3cm up to 200cm directly to your autopilot for reliable terrain tracking and close-proximity obstacle avoidance.

Specifications

• Operating Range: 3cm to 200cm
• Accuracy: ±2cm (3cm to 100cm), ±5% (100cm to 200cm)
• Field of View (FOV): 9°
• Operating Voltage: 3.0V – 3.6V DC
• Communication Interface: UART
• Measurement Unit: cm (Default)
• Dimensions: 20mm × 11.5mm × 7.6mm
• MPN: TF-LC02
• Weight: Data unavailable (the factory clearly misplaced their microgram scales, but it weighs virtually nothing on your airframe)

FAQ

What logic voltage does the TF-LC02 use?

The TF-LC02 runs on a 3.0V to 3.6V DC power supply, making it directly compatible with standard 3.3V logic microcontrollers and flight controller UART ports.

What is the effective measurement range of the TF-LC02?

The sensor delivers reliable Time-of-Flight distance measurements starting at a minimum distance of 3cm out to a maximum range of 200cm (2 metres).

Disclaimer

This optical laser rangefinder will deliver accurate altitude and proximity data, but it cannot fix bad PID loop tuning or prevent you from throttling into a tree. Solid mounting and correct UART configuration are entirely up to you.
