Benewake TF-Luna LiDAR Rangefinder — 0.2–8m, UART/I2C, 1–250Hz Adjustable, VCSEL 850nm, for Pixhawk, ArduPilot & Arduino UAV
The Benewake TF-Luna is a compact single-point LiDAR rangefinder module with a 0.2–8m operating range, designed for UAV altitude hold, terrain following, obstacle detection, and precision ranging applications. Using a VCSEL 850nm laser with a narrow 2° FOV, it delivers ±6cm accuracy at close range and ±2% accuracy at longer distances, with a 1–250Hz adjustable frame rate. Dual interface support (UART and I2C) makes it compatible with Pixhawk, ArduPilot, Arduino, Raspberry Pi, and any platform with a serial or I2C port. CE, FCC, and RoHS certified.
Key Features
- 0.2–8m Operating Range — Suitable for UAV altitude hold, terrain following, and close-range obstacle detection
- VCSEL 850nm Laser — Narrow 2° FOV for precise single-point distance measurement
- ±6cm Accuracy (0.2–3m) / ±2% Accuracy (3–8m) — High accuracy across the full operating range
- 1cm Range Resolution — Fine-grained distance data for precise altitude and proximity sensing
- 1–250Hz Adjustable Frame Rate — Configurable update rate for different application requirements
- UART & I2C Dual Interface — 3.3V LVTTL; compatible with Pixhawk UART/serial ports, Arduino, Raspberry Pi, and any I2C/serial host
- Compact & Lightweight — 16g; minimal impact on UAV payload
- Wide Operating Temperature — -20°C to +75°C for outdoor and industrial use
- CE / FCC / RoHS Certified
