NEO-M8N GPS with Compass for Pixhawk with extra connector for APM
The NEO-M8N is a professional-grade GPS module with integrated magnetometer compass designed specifically for autonomous flight control systems like Pixhawk and APM autopilots. This module provides centimeter-level positioning accuracy and real-time compass heading data essential for UAV navigation, stabilization, and waypoint-based autonomous missions. The dual connector design ensures seamless integration with both Pixhawk and APM flight controllers, making it the preferred choice for commercial drone operators, roboticists, and aerial surveying professionals worldwide.
Product Overview
The NEO-M8N GPS module operates on the u-blox M8 engine, utilizing multi-constellation GNSS technology that locks onto GPS, GLONASS, Galileo, and BeiDou satellite signals simultaneously for enhanced accuracy and faster acquisition times even in challenging environments. The integrated HMC5883L three-axis magnetometer provides compass heading data with 1-degree resolution, critical for maintaining aircraft orientation during autonomous flight. The module communicates via UART serial interface at 38400 baud rate and delivers position updates at 5Hz standard frequency, upgradeable to 10Hz for high-performance applications.
What distinguishes the NEO-M8N is its robust performance in GPS-denied environments with its built-in Assisted GNSS (A-GNSS) capability that downloads satellite ephemeris data for faster cold starts. The module features a ceramic patch antenna with integrated LNA (Low Noise Amplifier) for superior signal reception, and operates across a wide voltage range of 2.7V to 3.6V, making it compatible with standard 3.3V autopilot systems. The extra connector provision allows simultaneous connection to both Pixhawk and APM controllers, enabling redundant navigation systems or dual-autopilot configurations for mission-critical applications.

How to Use
Installation of the NEO-M8N GPS module requires connecting the module to your Pixhawk or APM autopilot via the GPS port using the provided connector. Mount the antenna away from metal surfaces and electronic noise sources, ideally on the top of your aircraft frame with clear sky visibility. The module requires 3.3V power supply which is typically provided by the autopilot's power management unit. Once powered, the module will begin acquiring satellite signals and the compass will calibrate automatically through the autopilot's calibration routine.
Configuration is performed through the autopilot's ground control station software such as Mission Planner or QGroundControl. Navigate to the GPS and Compass calibration sections to verify signal acquisition, set the update rate to 5Hz or 10Hz based on your application requirements, and perform compass calibration by rotating the aircraft in figure-eight patterns. The dual connector design allows you to connect both Pixhawk and APM simultaneously by using appropriate splitter cables if implementing redundant systems. Monitor the GPS signal strength and number of acquired satellites through the ground control station telemetry display to ensure optimal performance during flight operations.
Frequently Asked Questions
What is the difference between NEO-M8N and other GPS modules like NEO-6M?
The NEO-M8N features multi-constellation GNSS support (GPS, GLONASS, Galileo, BeiDou) compared to NEO-6M which supports only GPS and GLONASS. This provides faster acquisition times, better accuracy in challenging environments, and improved reliability. The M8N also has faster update rates up to 10Hz versus 5Hz on M6, making it superior for high-performance autonomous applications.
Can I use this GPS module with both Pixhawk and APM simultaneously?
Yes, the dual connector design allows simultaneous connection to both Pixhawk and APM controllers. However, you will need appropriate splitter cables to connect the single GPS module to both autopilots. This configuration is useful for redundant navigation systems where both autopilots receive identical GPS and compass data for failover protection.
How long does it take for the GPS to acquire satellites and achieve a lock?
With Assisted GNSS (A-GNSS) enabled and fresh ephemeris data, cold start acquisition takes less than 30 seconds. Warm start with valid ephemeris data takes approximately 5-10 seconds. Hot start with valid position and time data takes 1-2 seconds. The multi-constellation support significantly speeds up acquisition compared to single-constellation GPS modules.
What mounting orientation is recommended for the GPS antenna?
Mount the ceramic patch antenna facing upward toward the sky with clear line-of-sight to the horizon. Avoid mounting near metal surfaces, carbon fiber components, or electronic noise sources like power distribution boards. The antenna should be positioned at least 10cm away from the flight controller and other high-frequency electronic components to minimize electromagnetic interference.
Does the module require calibration before first use?
The GPS module itself requires no pre-calibration, but the integrated compass must be calibrated through your autopilot's ground control station. Perform a compass calibration by rotating the aircraft in figure-eight patterns in all three axes. This calibration corrects for local magnetic field variations and aircraft-induced magnetic distortions, ensuring accurate heading data.
When will I receive my order?
Orders are dispatched within 1-5 business days from our Bengaluru warehouse. Delivery takes 7-8 days to most locations across India.
What is your return and warranty policy?
We offer a 7-day return policy on manufacturing defects only. Contact support within 7 days of receipt for free replacement or full refund. Not applicable for user damage or misuse.
