EAI X3 Detailed Description



YDLIDAR X3 is a 360 degrees two-dimensional rangefinder (hereinafter referred to as X3) developed by EAI team. Based on the principle of triangulation, it is equipped with related optics, electricity, and algorithm design to achieve high-frequency and highaccuracy distance measurement. The mechanical structure rotates 360 degrees to continuously output the angle information as well as the point cloud data of the scanning environment while ranging.

Product Features

➢ 360 degrees omnidirectional scanning ranging distance measurement

➢ Small distance error, stable performance and high accuracy

➢ Wide Ranging distance

➢ Strong resistance to ambient light interference

➢ Low power consumption, small size and long service life

➢ Laser power meets Class I laser safety standards

➢ Adjustable motor speed


➢ Robot navigation and obstacle avoidance

➢ Robot ROS teaching and research

➢ Regional security

➢ Environmental scanning and 3D reconstruction

➢ Navigation and obstacle avoidance of robot vacuum cleaner/ROS Learning robot


Development Kit

The X3 development kit has the following components:


USB Adapter board has two USB TYPE C interface:USB_DATA、USB_PWR.

USB_DATA: Data powered interface. In most cases, this interface can be used to meet power and communication requirements.

USB_PWR: Auxiliary power supply interface. The USB interface of some development platforms has weak current drive capability. At this time, auxiliary power supply can be used.


Device Connection

When evaluating and developing X3 under windows, X3 and PC needed to be connected. The specific process is as follows:

Connect the adapter board with X3 first, then connect the USB cable to the USB port of the adapter board and the PC. Note that the Type-C interface of the USB cable is connected to the USB_DATA of the USB adapter board, and the X3 enters the idle modeafter being powered on. The motor does not rotate.

The drive current of USB interface of some development platforms or PC is not sufficient. X3 need to be connected to the auxiliary power supply of +5V, otherwise the lidar will be abnormal.

Performance Parameter

Note 1: It is factory FQC standard value, 80% reflectivity material object.

Note 2: The relative error value indicates the accuracy of the Lidar measurement. Relative error (mean value) = (average measured distance-actual distance)/actual distance *100%, sample size: 100pcs.

Note 3: Lidar is a precision device, please avoid using Lidar under high or low temperature or strong vibration situation, the relative error parameter index will be relatively larger, and it may exceed the typical value.


Electrical Parameter

Interface Definition

X3 provides a PHD1.25_4P receptacle with functional interfaces for system power, data communication and motor control.
