The LD19 is a compact 360° DTOF (Direct Time-of-Flight) LiDAR sensor with a ranging distance of up to 12 metres. It provides high-frequency environmental scanning for autonomous mapping, obstacle detection, and navigation. The sensor resists ambient light up to 30 kLux, enabling reliable operation both indoors and outdoors.
The included SDK supports ROS1 and ROS2, and the sensor communicates via UART at 3.3 V. A brushless motor drives the scanning mechanism for long-lasting, reliable operation.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- LiDAR
- A sensing method that uses laser light to measure distance and build a 3D picture of the surroundings. It matters for robotics and autonomous systems because LiDAR data can help with mapping, navigation and obstacle detection.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
