Holybro DroneCAN M9N GPS

The Holybro DroneCAN M9N GPS is equipped with a UBLOX M8N or M9N module, a BMM150 compass, and a tri-colored LED indicator. It features an STM32G4 processor and utilizes the DroneCAN protocol for communication, enhancing reliability and reducing susceptibility to electromagnetic interference compared to traditional serial connections. This setup frees up serial ports on the flight controller, and multiple CAN devices can be linked together on the same CAN bus through a CAN splitter board.

DroneCAN

DroneCAN is the main CAN protocol utilized by the ArduPilot and PX4 projects for interfacing with CAN peripherals. It is an open protocol featuring open communication, detailed specifications, and various open-source implementations.
