Readytosky M10 GPS Module External Compass with GPS Holder for Pixhawk 2.4.8 Flight Controller

What buyers think

Buyer-review evidence is limited, but a few recurring themes show up. Several users focus on GPS accuracy and practical integration, mentioning successful satellite acquisition and configuration verification workflows. Mounting convenience also appears in feedback, specifically the benefit of keeping the GPS away from other electronics for cleaner signal. There is also at least one report of a unit that initially worked well but later stopped picking up satellites, with resolution described through replacement support. Overall, buyer sentiment leans positive on performance and usability, while the compatibility requirement and occasional early reliability hiccup are the main decision caveats.

Key specs that matter for drone builders

This GPS module is aimed at autopilot navigation use, so the useful specs are about signal handling, update rate, integration method, and how configuration is preserved.

GNSS performance and update rate

• Positioning accuracy (ideal environment): 1.5 m CEP.
• Satellite concurrency: up to 3 satellites tracked concurrently (as listed).
• Navigation update rate: up to 10 Hz.
• Hot and cold start times (ideal environment): 1 s hot start, 26 s cold start.

Compass integration (external magnetometer)

The external compass uses sensor hardware listed as QMC5883/IST8310 (the specific model is described as being sent at random). In practice, the value is that the compass can be mounted where it is less affected by nearby electrical noise, compared with relying on a built-in magnetometer.

Interfaces, output protocols, and configuration storage

• Serial output baud rate: configurable range 4800 to 921600 bps, default 115200 bps.
• Output protocols: NMEA and UBX.
• Logic/output level: 3.3V TTL.
• Flash: onboard flash can store configuration changes and retain them when power is off.

Compatibility and setup considerations

This module is intended for Pixhawk 2.4.8 flight controller setups. That matters because GPS hardware and autopilot firmware often expect specific wiring, baud rates, and protocol behavior. The unit is explicitly not positioned for other flight controllers.

Power and physical mounting

• Working voltage: DC 3.6 to 5.5 V (typical 5.0 V).
• Included hardware: the package includes the GPS module and a black GPS holder.

Practical mounting advice from buyer feedback is to position the GPS away from other drone electronics when possible, since that can improve the quality of the navigation signal.

Pros and cons for different types of buyers

Best for

• Pixhawk 2.4.8 builders who want a GPS module that also brings an external compass for more predictable heading behavior.
• Hobbyists comfortable with serial data and configuration workflows (for example, using tools that can confirm satellite reception and output).
• Drone projects that benefit from a clean physical separation between the GPS and power or radio electronics.

Who should avoid it

• Anyone using a flight controller other than the supported Pixhawk configuration, since this module is not intended for general cross-compatibility.
• Buyers who cannot accommodate the possibility of early replacement if a unit fails to maintain satellite lock after setup.

Verdict

The Readytosky M10 is a purpose-built GPS and external compass module for Pixhawk 2.4.8 style autopilot builds. If you are specifically working in that ecosystem, the multi-GNSS support, configurable serial output (UBX and NMEA), and onboard flash for saved settings are practical advantages. Just be strict about compatibility, plan your mounting to reduce interference, and buy from a retailer with straightforward support in case you receive a defective unit.
