FIG 2 YDLIDAR G2/G4/G6
Connect the adapter board and Lidar first, and then connect the USB cable to the USB port on the
adapter board and the PC. Note that the USB cable is connected to the USB adapter's USB_DATA.
After the Lidar is powered on, it is in idle mode and the motor does not rotate.
The drive current of the USB interface of some development platforms or PCs is weak, and the
Lidar needs to access the +5V auxiliary power supply, otherwise it will work abnormally.
