HGLRC M100-5883 Compass Module, Upgraded 10th Generation Chip Compatible with FPV Fixed-Wing UAV
Quick take
The HGLRC M100-5883 is a small GPS module for UAVs that also includes a built-in QMC5883 compass, intended to reduce wiring and space compared to running separate GPS and magnetometer modules. Owners emphasize fast satellite lock and stable tracking once it connects, with the main buying caveat being that it needs proper calibration and careful soldering and wiring to avoid setup issues.
Pros and cons
Pros
- Integrated QMC5883 compass for direction sensing without a separate compass module
- Multi-constellation support (GPS, Galileo, BDS, plus others listed) aimed at strong performance across areas
- Compact and lightweight for FPV fixed-wing builds (about 21 mm x 21 mm, 7.73 g)
- Many owners report quick cold or hot starts and good satellite holding
Cons
- Setup matters, including compass calibration and careful wiring to match the expected connections
- Firmware and power requirements need to be met for best compatibility (lower firmware may not recognize the 10th generation chip)
- Compass and GPS performance can be affected by installation choices, such as proximity to high-current wiring
What buyers think
Buyer-review evidence is generally consistent on performance and install experience. Owners who upgrade FPV fixed-wing builds report that the module locks satellites quickly, including fast warm starts, and holds position with a stable number of satellites during typical flight behavior. The integrated compass is also frequently mentioned as a practical convenience because it can simplify the overall build by reducing the need for an extra magnetometer module. Setup success appears to depend on installation discipline, since some feedback points to wiring attention (connections not being clearly labeled) and the importance of keeping the GPS/compass away from interference sources like high-current wiring.
Who this GPS compass module is for
- FPV fixed-wing builders who want GPS and a compass in one compact package to support navigation and heading-related features.
- People upgrading an older GPS setup and looking for faster lock times and more reliable satellite tracking.
- Compact airframes where space and weight are tight, since the module is small and lightweight.
Who should skip it
- Buyers who do not want to do careful setup. If you prefer plug-and-play hardware, plan on taking time with calibration and wiring checks.
- Those using incompatible firmware or unclear wiring workflows. If your flight stack cannot meet the stated firmware and power expectations, you may have a rougher experience.
- Installers who place it near high-current electronics without thinking about interference. Proper mounting and cable routing matter for stable compass and GPS behavior.
Key features that matter in real builds
Integrated GPS plus QMC5883 compass
This module bundles satellite positioning with a magnetometer (QMC5883), which can streamline your wiring layout on fixed-wing FPV platforms. For projects that need both position and heading cues, the combined design can reduce the number of separate sensors you must physically mount and connect.
Multi-constellation positioning support
It supports multiple satellite systems and related augmentation modes (including the common GPS L1 family, plus Galileo and BDS, with additional systems listed). The intent is to improve satellite availability depending on location and sky view, which can translate to faster acquisition and more stable tracking when compared to single-constellation approaches.
Stable signal and compact hardware footprint
The GPS hardware uses a ceramic antenna design and an external expansion PCB approach, aiming to receive satellite signals effectively while staying small. With a compact size around 21 x 21 mm and low weight, it is designed for builds where you cannot spare much mounting area.
Output rate and compatibility expectations
The module supports selectable update behavior, including an output frequency range (1 Hz to 10 Hz, with a default listed at 10 Hz). Make sure your flight controller and firmware configuration align with the connection method and power requirements, since reliable recognition depends on meeting those conditions.
Setup caveats buyers actually run into
- Calibrate the compass after power-on. Compass calibration is explicitly required before use, and it is central to getting trustworthy heading behavior.
- Wire and solder carefully. Some buyers note that it is easy to mix up connections when wiring the harness, so double-check orientation before applying power.
- Keep away from interference. Guidance for better performance includes mounting away from high-current wiring to reduce magnetic and electrical interference.
- Match firmware expectations. Using firmware older than the specified minimum can prevent recognition of the 10th generation chip, so confirm your flight stack version before installing.
Pros and cons summary
- Best for: FPV fixed-wing builds that want GPS and compass in one small unit, with an emphasis on faster satellite lock and stable tracking.
- Not ideal for: buyers who want zero-effort setup, or anyone unwilling to do calibration and careful wiring checks.
- What to verify before buying: your firmware version meets the minimum expectations, your wiring plan matches the module’s connection method, and your mounting location avoids high-current interference.
Price and availability
Pricing can vary, so check the current listing for the most accurate cost and shipping details. If you are comparing options, focus less on the sticker price and more on setup friction and whether the integrated compass meets your build’s sensor layout goals.

FAQ
Does the HGLRC M100-5883 include a compass?
Yes. It includes an integrated QMC5883 compass, intended to provide direction information along with GPS positioning.
How fast does it get a GPS lock?
Buyers report quick satellite acquisition, including fast warm starts, and stable satellite holding once the module has locked.
Do I need to calibrate the compass?
Yes. After powering on, you should calibrate the compass before using it for accurate direction readings.
Will it work with Betaflight?
It is commonly used with flight-controller setups in the FPV ecosystem. Ensure your Betaflight (or other flight firmware) version meets the stated minimum requirement so it can recognize the 10th generation chip.
Is the wiring difficult?
Wiring requires care. Some buyers mention that the harness orientation is not obviously labeled, so verify connection placement before powering the module.
Will mounting location affect performance?
Yes. Performance guidance includes keeping the module away from high-current wires to minimize interference that can affect both GPS and compass behavior.
What update rate does it output?
The module supports an output frequency range of 1 Hz to 10 Hz, with a default listed at 10 Hz.
Bottom line
The HGLRC M100-5883 is a practical choice for FPV fixed-wing pilots who want GPS and an integrated compass in a compact, lightweight module. If you take the setup seriously (compass calibration, careful wiring, and interference-aware mounting), the overall buyer experience centers on fast locking and stable satellite tracking.
