IMU MPU6050

EAI X2L LiDAR

The YDLIDAR X2L LiDAR is a 360 degree two-dimensional ranging product developed by Shenzhen EAI Technology Co., Ltd. (EAI). This product is based on the principle of trigonometric ranging and is equipped with related optical, electrical, and algorithm design to achieve high-frequency and high-precision distance measurement. While measuring distance, the mechanical structure rotates 360 degrees and continuously obtains angle information, thereby achieving 360 degrees scanning distance measurement, and output point cloud data of the scanning environment.
