NEO 3X GPS Module Parameters and Interfacing Instructions

NEO 3X is a GNSS receiver with IP66 protection. It supports four-star system integration and features a variety of built-in waterproof and dustproof structural designs and materials to meet requirements in various environments. It has a built-in STM32F4 series processor, an ICP2100 barometer, a Ublox M9N module, and an RM3100 industrial-grade electronic compass, and supports the DroneCan protocol.

Note
ArduPilot 4.0 and higher firmware fully supports NEO 3X.
