Product description
The SparkFun SAM-M10Q GPS Breakout features the SAM-M10Q chip-antenna module from u-blox. The M10Q line is the successor to u-blox's M8Q found on the SparkFun GPS Breakout - Chip Antenna, SAM-M8Q (Qwiic), and is a drop-in replacement with updated features to reduce power consumption by almost half while also improving performance and accuracy. The SAM-M10Q can receive up to four GNSS constellations at once which improves time-to-fix and positional accuracy even in areas with a limited view of the sky.
The SAM-M10Q includes a built-in chip antenna and is compatible with the L1 band on all five GNSS constellations (GPS L1 C/A, QZSS L1 C/A L1S, GLONASS L1OF, BeiDou B1C, and Galileo E1B/C). It has a horizontal position accuracy of 1.5m, a max update rate of 18Hz when transmitting with just one GNSS constellation (max of 5Hz with four GNSS), and a cold start time to fix of 23 seconds. The board includes a rechargeable 3V/1mAh battery to provide backup power for up to four hours to maintain a hot start of just a single second.
