Holybro DroneCAN M8N GPS

DroneCAN carries GPS data over the same robust CAN bus protocol used elsewhere in professional drone builds, which holds up better against electrical noise over longer cable runs than a standard UART GPS connection - a real concern on bigger aircraft where the GPS mast sits well away from the flight controller. Built around the u-blox M8N receiver, it delivers the positioning accuracy that chipset is known for while gaining DroneCAN's noise immunity and simpler multi-device bus wiring. A sensible upgrade path for anyone building a larger or more electrically noisy airframe where a standard UART GPS has started showing intermittent data issues.
