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.
We designed this board to integrate into the Qwiic system that requires no soldering to connect it to the rest of your I2C system. However, the board still breaks out 0.1"-spaced pins for users who prefer a soldered connection or prototyping on a breadboard.
U-blox-based GPS products are configurable using the Windows program called u-center2 (it is highly recommended to only use u-center2 with this board and not the original u-centre). This program lets you customize all sorts of settings for the SAM-M10Q including baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. We also have an Arduino library for configuring the SAM-M10Q.
