Basic information

Connection

Use the “Embedded board” since I don’t have the “USB2LDS”. but you’ll need something to read uart from the LIDAR. And the second image, create connection with wire between LDS vcc and motor Vcc, LDS pwm and motor pwm.

USB2LDS vs basic uart

internal connection

This is my setup pretty simple (simpler than looking to find USB2LDS which I have none). I’m using cp2102, that one lying on my desk, I don’t know whether it would work with other (I supposed it would work as long as it recognized on your system as /dev/ttyUSB0
