Descriptions：
The Holybro DroneCAN GPS has an UBLOX M8N or M9N module, BMM150 compass, tri-colored LED indicator. It has adopted the DroneCAN protocol for communication. It is better in dealing with electromagnetic interference compare to serial connection, making it more reliable. It does not occupy any serial port of the flight controller, and different CAN devices can be connected to the same CAN bus via a CAN splitter board.
