Rplidar A3 USB connection

I am trying to connect RPlidar A3 on my navio2 from USB What is the configuration and connection for RPLIDAR?

Hi @edd9615,

To connect RPLidar to Navio2 using USB, please, follow these steps:

  • First, specify some launching options:

    TELEM2="-D /dev/ttyUSB0"

  • Then, using Mission Planner, set:
    SERIAL2_BAUD = "57"

Also, there is a guide about ArduPilot and RPLidar A2 integration in the ArduPilot docs. This should apply to RPLidar A3 as well.

Hi @svetlana.nikolenko
rplidar a3 is not rotating the configuration is shown in the images

I followed the steps on this page but had no results with BAD LIDAR Heatlh error


Hi @edd9615,

According to the ArduPilot docs, this message appears because the rangefinder isn’t enabled for landing.

To get rid of this, you need to set the RNGFND_LANDING parameter.
