Matek Neo M9N-5883 GNSS + Compass Module

M9N-5883 uses multi-constellation GNSS powered by u-blox NEO-M9N , NEO-M9N is a concurrent GNSS receiver which can receive and track multiple GNSS systems. Owing to the multi-band RF front-end architecture all four major GNSS constellations, GPS,Galileo, GLONASS and BeiDou can be received concurrently.

As of now (October 2020) Ardupilot firmware supports the Neo-M9N module, but Inav and Betaflight do not, but support will be added.  If you want to use this with Inav/Betaflight you will need to select NEMA protocol on the module.
