The MATEKSYS AP Periph GNSS M10-L4-3100 GPS Navigation Module from Matek is a compact, lightweight, and high-precision GNSS peripheral module with an integrated compass and barometer, designed for use in drones and other unmanned platforms. The device runs on ArduPilot AP_Periph firmware and provides reliable positioning and spatial orientation thanks to modern components and a wide range of interfaces. Product type: Drones & Quadcopters > Drone Accessories.

Features and Purpose

The M10-L4-3100 is a GNSS+COMPASS+BAROMETER peripheral device equipped with CAN/DroneCAN and UART/MSP interfaces, allowing for easy integration into ArduPilot-supported autopilot systems. The multi-system GNSS receiver based on u-blox MAX-M10S simultaneously receives GPS, GLONASS, Galileo, and BeiDou signals, enhancing positioning stability and accuracy in challenging conditions and during intensive platform maneuvering.

Explanation of Key Components

The u-blox MAX-M10S is a parallel multi-system GNSS receiver that allows simultaneous tracking of signals from multiple satellite systems to improve position accuracy and fix speed. The PNI RM3100 compass provides high resolution, low power consumption, no hysteresis, and a large dynamic range—critical parameters for agile aircraft. The SPL06-001 barometer provides additional altitude information, improving stabilization and navigation in the vertical plane.

Interfaces and Integration

The module supports MSP protocols over UART2 and DroneCAN over CAN, making it compatible with modern flight controllers and the ArduPilot peripheral network. The presence of UART3 for the built-in MAX-M10S simplifies GNSS configuration, and the I2C JST-GH connector allows for the connection of an external airspeed sensor. Thanks to the ArduPilot AP_Periph firmware, installation and configuration in most systems do not require additional hardware modifications.

Package Contents

• 1× M10-L4-3100
• 2× JST-GH-4P — 20 cm silicone wire
