Micro M10 GPS Module (without Case), u-blox M10, IST8310 Compass

This Micro M10 GPS module is built around the u-blox 10th-generation GNSS chip, a multi-constellation receiver that tracks GPS, Galileo, GLONASS and BeiDou satellites simultaneously rather than relying on a single satellite system, which gives more reliable fixes especially in partially obstructed sky-view conditions common on a flying drone banking and turning. An IST8310 compass is built into the same module, providing heading data alongside position so a flight controller can orient the aircraft correctly during GPS-assisted flight modes.

The module includes a 25x25mm patch antenna with omnidirectional radiation, giving flexible mounting orientation since the antenna doesn't need to be precisely aimed to receive a strong signal, unlike some directional antenna designs. Active antenna circuitry boosts the incoming signal before it reaches the GNSS chip, and a rechargeable backup battery keeps enough state saved to enable a fast warm start the next time the module powers on, rather than needing a full cold-start satellite search every single flight.

This being the "without case" version means the bare module and antenna assembly ship without an external housing, suiting builders who are mounting it inside their own enclosure or who prefer the reduced weight of skipping an unnecessary extra shell. Firmware compatibility covers PX4 1.14, ArduPilot 4.3, INAV 5.0.0 and Betaflight 4.3.0 or newer, so it's worth confirming a flight controller's firmware version meets that minimum before relying on this module for GPS-assisted flight modes.

Builders who want this generation of multi-constellation GPS performance without paying for or carrying the weight of an external case, perhaps because the module will be mounted inside a canopy or 3D-printed housing of their own design, will find this bare module version the appropriate choice.
