HGLRC M100 Pro GPS Module

The HGLRC M100 Pro is a 10th-generation GNSS module designed for FPV freestyle rigs, long-range cruisers, and heavy-lift cinelifters. Powered by the u-blox M10 engine and equipped with an integrated digital magnetometer, it delivers rapid satellite acquisition and precise directional heading. This module provides stable, reliable coordinates required for accurate Betaflight GPS Rescue mode, INAV Return-to-Home (RTH), and autonomous waypoint navigation.

Key features

• Powered by the 10th-generation u-blox M10 GNSS architecture for concurrent reception across GPS, GLONASS, Galileo, and BeiDou constellations.

• Integrated QMC5883L magnetometer over I2C provides accurate compass heading data essential for RTH accuracy and position hold.

• High-gain ceramic patch antenna maintains superior signal lock and fast cold-start acquisition times, even during aggressive banking manoeuvres.

• Runs on standard 5 V power with a pre-configured 115200 bps baud rate and UBLOX output protocol for seamless plug-and-play flight controller integration.

• Compact, low-profile footprint engineered to mount securely on 3D-printed TPU tail mounts without disrupting overall frame centre-of-gravity.

Compatible with Betaflight, INAV, and ArduPilot firmware, the M100 Pro connects directly to your flight controller via standard 6-pad UART and I2C wiring (TX, RX, SCL, SDA, 5V, GND). For optimal performance, ensure the module is mounted with the ceramic antenna facing skyward and positioned away from high-current battery leads or video transmitters to minimise electromagnetic interference.
