YDLIDAR X2N LiDAR
Overview
YDLIDAR X2N is a 360° two‑dimensional distance measurement LiDAR developed. Based on the triangulation principle and combined with optical, electrical, and algorithmic designs, it achieves high‑frequency, high‑precision ranging. While measuring distances, the mechanical structure rotates 360° to continuously acquire angle information, outputting point cloud data of the scanned environment. It is widely used in robot navigation, obstacle avoidance, security surveillance, and 3D reconstruction.
Key Features
- 360° Omnidirectional Scanning – Full coverage with no blind spots, delivering complete point cloud data.
- High Accuracy & Stability – Low ranging error and strong resistance to ambient light interference.
- Wide Ranging Range – Typical 0.12 m ~ 8 m indoors (80% reflectivity).
- Laser Safety – Complies with Class I laser safety standard (IEC 60825-1), safe for human eyes.
- Adjustable Motor Speed – Supports external PWM signal for scan frequency adjustment (5 Hz ~ 8 Hz).
- Low Power & Compact Size – Typical operating current 350 mA, weight only 116 g, easy to integrate.
Applications
Robot navigation and obstacle avoidance; ROS education and research; area security monitoring; environmental scanning and 3D reconstruction; home service robots (e.g., vacuum cleaners) navigation and obstacle avoidance.
Detailed Description
The YDLIDAR X2N employs triangulation ranging technology, performing 3000 measurements per second (measurement frequency 3000 Hz) to rapidly capture the surrounding environment. The scan frequency can be flexibly adjusted via the PWM signal on the M_CTR pin (5 Hz ~ 8 Hz) to suit different applications. In terms of accuracy, the absolute error is ≤ ±2 cm for distances ≤ 1 m; relative error ≤ 3.5% for 1 m < distance < 6 m; and ≤ 5.0% for 6 m ≤ distance ≤ 8 m, ensuring reliable and precise data.
The electrical interface uses an MX1.25‑4P female connector, providing 5 V power (4.8 V ~ 5.2 V), serial communication (Tx, 3.3 V logic, baud rate 115200 bps), and motor speed control (M_CTR). By controlling the M_CTR pin level or PWM signal, the radar can be put into standby or operating mode, and its rotation speed can be adjusted. The internal optical system uses an infrared pulse laser with wavelength 775 nm ~ 800 nm and average output power ≤ 13 mW, meeting Class I safety requirements—no additional protective measures are needed.
The operating temperature range is 0 ℃ ~ 40 ℃, storage temperature -10 ℃ ~ 60 ℃, ensuring stable operation in typical indoor environments. The polar coordinate system is defined with the rotation center as the pole, clockwise as positive angle, and the zero‑angle at the front of the motor (with an individual deviation of ±3°), facilitating data parsing and secondary development.
