CUAV NEO 3 GPS Module | GNSS U-blox M9N Drone Hardware

The CUAV NEO 3 GPS Module with u-blox M9N is an integrated GNSS and compass unit designed for unmanned aerial vehicles, autonomous robotics, and compatible flight-control systems. It combines satellite positioning, electronic heading measurement, RGB status lighting, an audible buzzer, and a physical safety switch in one compact assembly.

By supporting four major satellite navigation systems simultaneously, the NEO 3 helps compatible flight controllers obtain navigation data for flight monitoring, position control, and autonomous missions. Its integrated compass provides heading information, while the status indicator and buzzer can communicate system states and alerts.

Features

• u-blox M9N GNSS Receiver: Provides satellite positioning for UAV navigation and tracking.

• Four-System Satellite Reception: Supports GPS, GLONASS, BeiDou, and Galileo simultaneously.

• Integrated IST8310 Compass: Supplies electronic heading data to a compatible flight controller.

• Up to 25Hz Navigation Updates: Supports high-frequency navigation output according to the published specifications.

• RGB Status Indicator: Provides visual flight-controller status feedback.

• Integrated Buzzer: Supports audible status and warning functions.

• Physical Safety Switch: Provides a dedicated safety-control interface for compatible flight-control systems.

• Interference-Filtering Design: Uses a triple-filter arrangement and EMI/RFI protection measures.

• Firmware Upgrade Support: Allows supported GNSS receiver firmware upgrades.

• Compact Construction: The 60 × 60 × 16mm design suits many multirotor and fixed-wing UAV builds.

Applications

• Multirotor FPV and professional UAV platforms

• Pixhawk-based drone navigation systems

• Fixed-wing unmanned aircraft

• Autonomous flight and waypoint missions

• Robotics and unmanned vehicle navigation

• Drone development, testing, and research

• UAV positioning and heading measurement projects

How to Use

1. Check compatibility: Confirm that your flight controller supports the CUAV NEO 3 and its required interfaces.

2. Mount the module: Install it in a suitable location with the GNSS antenna unobstructed and away from strong sources of electromagnetic interference.

3. Connect the cable: Use the correct connector and wiring arrangement for your flight controller. Verify the pinout before applying power.

4. Power the module: Supply the specified 4.7–5.2V DC input through the appropriate port.

5. Configure the flight controller: Use the compatible firmware and follow the controller manufacturer's instructions for GPS and compass detection.

6. Calibrate the compass: Follow the flight-controller calibration procedure and verify the configured compass orientation.

7. Test before flight: Check satellite reception, position reporting, heading accuracy, status indicators, buzzer behavior, and safety-switch operation before flying.

Important Notes

• The NEO 3 is a complete GNSS and compass assembly, not just a standalone GPS receiver.

• Ensure that the flight controller and firmware support this specific NEO 3 model. Verify PX4 or ArduPilot compatibility for your particular setup before purchase.

• Use only the specified input voltage and compatible cable pinout.

• Install the module away from high-current power wiring, ESCs, motors, and other potential interference sources.

• GNSS positioning and compass performance depend on installation quality, satellite visibility, and environmental interference.

• The published 2.0m horizontal accuracy is a specification under stated conditions, not a guarantee of real-world performance.

• Confirm the package contents with the seller; connecting cables and additional accessories may vary.

Package Includes

• 1 × CUAV NEO 3 GPS / GNSS Module
