CHART 4 YDLIDAR X4 SERIAL SPECIFICATIONS Item Min. Typical Value Max. Unit Baud rate - 128000 - bps Signal high 1.8 3.3 3.5 V Signal low 0 0 0.5 V Remark 8 data bits, 1 stop bit, no parity When the signal voltage is >1.8V, it is high level When the signal voltage is <0.5V, it is low level Motor control X4 comes with motor speed control motor driver. The peripheral can control the motor of X4 by inputting the control signal via two pins M_EN and M_SCTR in the interface.
Optical characteristics The X4 uses infrared point pulsed lasers that meet FDA Class I laser safety standards. When the system is working, lasers and optical lenses complete the transmission and reception of laser signals to achieve high-frequency ranging. To ensure the performance of the system ranging, please make sure that the X4's laser and optical lens are kept clean. The laser optical parameters are as follows: CHART 6 YDLIDAR X4 OPTICAL Item Laser wavelength Laser power FDA Min. Typical Value Max.
