The LDROBOT D800 (STL-27L) is a 360° Direct Time-of-Flight (DToF) LiDAR sensor built for autonomous robots, AGVs and SLAM navigation systems. It scans up to 25 metres in a full circle at 10Hz, streaming 21,600 laser samples per second to ROS1, ROS2, Raspberry Pi, NVIDIA Jetson and other embedded platforms for real-time mapping, localisation and obstacle avoidance.
The D800 is a compact 2D laser scanning module that measures distance by timing the direct flight of a low-power infrared laser pulse (DToF ranging). As the internal coaxial brushless motor spins the optical head through a full 360° rotation, the sensor outputs a dense, real-time point cloud describing everything around it making it a popular choice for robot navigation sensor upgrades where longer range and outdoor performance are required. Because it is FDA Class 1 certified, the laser is safe for use around people and pets in warehouses, offices and public spaces.

Key Features & Benefits
Long-range 360° scanning
measures from 0.03m out to 25m on reflective targets (10m on low-reflectivity/black objects), giving robots earlier warning and more time to plan a path.
High-speed sampling
21,600 samples per second at a 10Hz scan rate for a dense, detailed point cloud with 0.5° angular resolution.
Strong outdoor performance
60,000 Lux ambient light resistance keeps the sensor stable in direct sunlight, unlike many indoor-only LiDAR units.
Eye-safe laser
FDA Class 1 rated, low-power modulated pulse emitter safe for use near people.
Industrial-grade motor
coaxial brushless motor rated for 10,000 hours of continuous, low-noise operation.
Plug-and-play ROS support
native ROS1 and ROS2 drivers, plus compatibility with Raspberry Pi, NVIDIA Jetson, Windows, Ubuntu/Linux and industrial PCs.
Compact, lightweight housing
A small footprint suits mini robots as well as large AGVs, and can be mounted inside the chassis to save space.

Compatible Platforms & Integration
The D800 is designed for fast integration into existing robotics stacks. It ships with ROS1 and ROS2 driver support and connects over a serial/UART interface via the included USB adapter board, so it can be brought up on a Raspberry Pi, NVIDIA Jetson board, a Windows or Ubuntu/Linux PC, or an industrial control computer without custom hardware.
Frequently Asked Questions
What is the maximum range of the LDROBOT D800 LiDAR sensor?
The LDROBOT D800 (STL-27L) measures from 0.03m out to 25m on high-reflectivity targets, and up to 10m on black or low-reflectivity (≤10%) surfaces.
Is the D800 LiDAR compatible with ROS2?
Yes. The D800 has native driver support for both ROS1 and ROS2, so it can be integrated directly into existing robot navigation and SLAM stacks.
Can the D800 LiDAR sensor be used outdoors?
Yes. It is rated to 60,000 Lux ambient light resistance, which allows it to keep scanning reliably in direct sunlight rather than being limited to indoor use.
Is the D800 LiDAR laser safe for use around people?
Yes. The D800 uses a low-power, modulated-pulse infrared laser that meets the FDA Class 1 eye-safety standard.
What computers or boards can the D800 connect to?
The D800 connects over serial/UART via the included USB adapter board and works with Raspberry Pi, NVIDIA Jetson boards, Windows and Ubuntu/Linux PCs, and industrial control computers.
What is included with the LDROBOT D800 LiDAR kit?
Each kit includes the D800 LiDAR unit, a USB-to-serial adapter board, a USB cable, a 5-pin connector cable and a printed user manual.
