The YDLIDAR X4PRO 360 degrees 2D Rangefinder is a 360 degrees two-dimensional rangefinder (hereinafter referred to as X4PRO) developed by the 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 measurements. 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.

X4PRO provides a PH2.0-8P receptacle interface with functional interfaces for system power, data communication, and motor control. X4PRO uses a 3.3V serial port (UART) for duplex communication, and only supports one-way communication (Tx) for data downlink. The user can connect the external system and the product through the physical interface on the product, and communicate in accordance with the system communication protocol to obtain the scanned point cloud in real time.

X4PRO is a motor driver with its own motor speed regulation function. M_CTR is the motor speed control signal, which can be used for voltage speed regulation and PWM wave debugging. The lower the voltage/PWM duty cycle, the higher the motor speed. 0V / Maximum speed at 0% duty cycle.
