Lightware SF02 lidar and Pixhawk

Hi everyone,

Has anyone ever had any issues with interfacing the SF02 Lidar with Pixhawk 3.3V A/D port ?

I got 3 Lightware SF02s, 2 Pixhawks and only one SF02 works has described in . The 2 other SF02 have to be powered with a BEC and connected to +5V and GND screw terminals to make them working properly.
