2.4 Data Communication
With a 3.3V level serial port (UART), users can connect the external system and the
product through the physical interface. After that, you can obtain the real-time scanned
point cloud data,device information as well as device status.The communication protocol of
parameters are as follows：

2.5 Motor Control
X2 has its own motor driver with motor speed control function. The peripheral can
control the X2 motor by inputting control signals through the M_CTR pin in the interface.
M_CTR is the motor speed control signal, which can be adjusted by voltage and can also
be debugged by PWM wave. The higher the voltage/the greater the PWM duty cycle, the
higher the motor speed.
Among them, the PWM signal of M_CTR has the following requirements:

2.6 Optical Characteristic
X2 uses an infrared laser that meets FDA Class I eye safety standards. The laser and
optical lens finish the transmission and reception of the laser signal to achieve high-
frequency ranging while working. To ensure system ranging performance, please keep the
laser and optical lens clean. The detailed optical parameters are as follows:
