Good day,
I did the setup as instructed on https://ardupilot.org/copter/docs/common-benewake-tf02-lidar.html and everything works perfectly but only while the USB is connected to the pixhawk.
As soon as I disconnect the USB to power everything from the battery then the SE100 GPS does not go on nor the PW_Link and the TF02 is also dead. As soon as I power off and disconnect the LiDAR then the GPS and PW link works again.
Could it be a serial clash as I did change it from serial 4 to serial 5 to check but it works on both as long as the USB is pluged in. Maybe the lidar draws too much power from the pixhawk power supply?
