M9N GPS HolyBro Original

Holybro M9N GPS Module – High-Precision Multi-Constellation GNSS for PX4 & ArduPilot

The Holybro M9N GPS is a next-generation, high-performance GNSS module designed for Pixhawk and other professional flight controllers. Powered by the u-blox NEO-M9N chip, it supports all major satellite constellations — GPS, GLONASS, Galileo, and BeiDou — offering exceptional accuracy, faster satellite acquisition, and improved positioning reliability in all environments.

With its integrated IST8310 compass, high-gain active antenna, and robust shielding, the Holybro M9N delivers stable and interference-free performance, even in electrically noisy drone builds. It’s an ideal companion for PX4 and ArduPilot-based UAVs, enabling precise navigation, waypoint missions, and autonomous flight control.

The module includes a 6-pin JST-GH connector for direct Pixhawk compatibility, an LED indicator, and a built-in safety switch for simple and reliable setup.
