Last updated 3 months ago

Connection to Autopilot

Wiring

The ARK Flow is connected to the CAN bus using a Pixhawk standard 4 pin JST GH cable. For more information, refer to the instructions.

Multiple sensors can be connected by plugging additional sensors into the ARK Flow’s second CAN connector.

Mounting

The recommended mounting orientation is with the connectors on the board pointing towards back of vehicle, as shown in the following picture.

ARK Flow align with Pixhawk

Connection to Autopilot

  • Connect the sensor to the autopilots’ CAN port

To use the onboard lidar:

Additional Notes

ArduPilot Setup Instructions

Set = 6 (DroneCAN)

Set = 1 to enable DroneCAN

Set = 1 (DroneCAN)

Set = 24 (DroneCAN)

Set = 5000 to set range finder’s maximum range to 50m

does not require the use of a rangefinder

Performance can be improved by setting the . For example if the sensor is mounted 2cm forward and 5cm below the frame’s center of rotation set to 0.02 and to 0.05.
