7Semi NEO-M9N GPS Breakout (Precision GNSS)

A precise breakout for drones and robotics

The 7Semi NEO-M9N GPS Breakout is a high-precision GNSS receiver built on the u-blox M9 engine. It supports GPS, GLONASS, Galileo and BeiDou with an accuracy of about 1.5 m and a 92-channel receiver. An onboard rechargeable battery allows a hot start in just 2 seconds.

Its security features stand out: it can detect and report jamming and spoofing events, which matters for autonomous vehicles and drones that depend on a trustworthy position.

How you can use it

The module speaks NMEA, UBX and RTCM protocols over UART or I2C, so it works with flight controllers, microcontrollers and single-board computers. Functions such as geofencing and spoofing detection can be configured in software, using u-blox's u-center tool.

For the best performance, place it away from the flight controller's noisy power lines and video transmitters, with a good active antenna and a clear sky view. For flight controllers such as ArduPilot and PX4, set the port to UBX and select the right baud rate.

Who it is for

Drone builders, robotics developers and researchers who want a modern u-blox M9 receiver on a convenient breakout.

Flight controller setup

When you use the module with a flight controller, set the port to accept UBX or NMEA at the module's baud rate and enable GPS in the flight controller software. Keep the module and its antenna well away from the video transmitter, ESCs and power leads, and place the antenna on top of the aircraft with a clear view of the sky.
