OVERVIEW

YDLIDAR X4PRO is a 360 degrees two-dimensional rangefinder (hereinafter referred to as X4PRO) 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 high- accuracy 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.

Development Kit

The X4PRO development kit has the following components：

Note:

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 X4PRO under windows, X4PRO and PC needed to connected.The specific process is as follows:

Connect the adapter board with X4PRO 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.

The drive current of USB interface of some development platforms or PC is not sufficient.X4PRO need to be connected to the auxiliary power supply of +5V, otherwise the lidar will be abnormal.

Installation and Dimensions

Performance Parameter

Note 1:The measurement range and relative accuracy above are the factory FQC standard value based on 80% reflectivity 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, which might cause an exceeded relative error.
