Description

丨 Product Introduction

AK3100 Industrial Geomagnetic Sensor: RM3100 core, IP68, -40℃ to 85℃, DroneCAN/UAVCAN compatible, elevates navigation accuracy for drones & robots.

characteristic:

Superior core performance: Using the industry-leading RM3100 magnetometer core, it provides high-precision, low-noise 3D magnetic field measurement.
Advanced communication interface: Supports DroneCAN/UAVCAN bus protocol, seamlessly integrates with mainstream flight control systems such as ArduPilot and PX4.
Sturdy and lightweight structure:It adopts an aluminum shell, weighs only 42.2 grams, and has a small volume (50 × 35 × 14mm), making it easy to integrate and install.
Good system compatibility: specially optimized for ArduPilot/PX4, plug and play, reducing integration and debugging costs.
Power supply and interface specifications: 5V DC power supply, standard GHR-04V-S interface and 50cm outlet for easy connection and wiring.

Key Advantages

Stable Navigation with Industrial-Grade Magnetometer
Built around the RM3100 sensor, this module delivers high magnetic sensitivity and low noise for dependable heading data in demanding environments. The 80Hz output rate helps maintain fast response during motion, while IP68 protection adds resistance against dust and water exposure. It is a practical choice for builds that need a durable external compass module with consistent signal quality and strong environmental tolerance. Designed for integration with drone flight controller systems, it supports precise orientation feedback for complex airframes. It also fits px4 flight control setups where stable navigation and reliable compass input are essential.

Flexible System Integration for UAV and Robotics
The AK3100 architecture is made for clean installation on platforms that need a separated sensing unit away from electrical interference. Its DroneCAN communication helps simplify wiring and supports more stable data transmission across larger systems. This makes the unit well suited for advanced UAV builds, autonomous machines, and field equipment that require dependable heading references. As a dronecan compass, it is easy to place in a better magnetic position than onboard sensors. It pairs well with an external compass module design philosophy for builders seeking accurate navigation input and practical layout flexibility.

Use Scenarios

UAV Navigation for Mapping and Inspection Missions
This module is well suited for multirotor and fixed-wing aircraft used in surveying, route planning, and infrastructure checks. The RM3100 sensor helps provide stable heading information when flying near metal structures or in changing magnetic conditions. Operators can rely on an drone flight controller setup for accurate orientation data during autonomous missions. In a px4 flight control system, the compass helps maintain consistent course behavior for professional aerial work where navigation accuracy matters.

Robotics and Industrial Platform Orientation Control
For ground robots, inspection carts, and other autonomous equipment, this compass supports reliable heading awareness in indoor and outdoor environments. Its IP68-rated housing is useful in dusty sites, field operations, and locations with occasional moisture exposure. The unit can be deployed as a dronecan compass on integrated platforms that need stable communication and flexible sensor placement. It also works as an external compass module for systems where separating the magnetometer from power electronics improves orientation stability.

FAQ

Q1. Is this compatible with my PX4 flight control setup?
Yes, it is designed for use with px4 flight control systems. We also support ArduPilot-based setups, so teams can integrate it into a drone flight controller architecture for navigation and compass data where that interface is required.

Q2. What role does the external compass module play in navigation?
The external compass module provides magnetometer input for heading reference in UAV navigation. Its RM3100 sensor and AK3100 magnetometer are intended to support stable orientation data, while our IP68 protection rating helps it suit demanding field conditions.

Q3. Can I use it in industrial or outdoor environments?
The unit is built with IP68 protection, so it is well-suited to harsher outdoor exposure and industrial robotics use. We recommend verifying your system enclosure, cable routing, and mounting method to match your operating environment and integration requirements.

Q4. What performance details should I review before integration?
It operates at an 80Hz rate, which is useful when selecting a dronecan compass for responsive heading feedback. Our team recommends matching update expectations, controller support, and calibration workflow with your existing UAV or robotics platform.

Q5. Do you provide technical support for installation and setup?
Yes, we support buyers during integration with product information for ArduPilot and PX4 use cases. Installation typically depends on your platform design, and we advise checking wiring, mounting location, and calibration needs before deployment.
