Compact Multi-GNSS Positioning with Built-In Chip Antenna
The GPS Breakout Chip Antenna SAM-M8Q SparkFun is a Qwiic-ready GNSS board built around the u-blox SAM-M8Q for compact positioning, timing, and navigation projects.
It combines a built-in smart antenna design with multi-constellation support, backup power for faster hot starts, and both Qwiic and breadboard-friendly connections.
Important: This board uses 3.3V logic and is built for GNSS projects that need a compact all-in-one receiver without an external antenna cable.
Why you'll love it
- 72-channel GNSS engine: Tracks multiple constellations for better coverage
- Built-in smart antenna design: Helps avoid bulky external RF wiring
- Qwiic connectors: Fast I2C hookup with no soldering
- Backup battery support: Speeds hot starts and preserves orbit data
- Breadboard breakout pins: Flexible for both quick prototypes and custom wiring
What you can build
Use it in trackers, loggers, location-aware devices, timing builds, mapping tools, and compact navigation projects.
Starter bundles
Pair it with a Qwiic microcontroller, Qwiic cable, data logger, and enclosure if you want a neat GNSS build with fast setup.
Recommended add-ons
Helpful add-ons include Qwiic cables, microcontrollers, data loggers, and libraries or host software for configuration.
