GPS Breakout, ZOE-M8Q, Qwiic – Sparkfun GPS-15193
The SparkFun ZOE-M8Q GPS Breakout is a high accuracy, miniaturized, GPS board that is perfect for applications that don’t possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, BeiDou, and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery you’ll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don’t have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.
U-blox based GPS products are configurable using the popular, but dense, windows program called u-center. Plenty of different functions can be configured on the ZOE-M8Q: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. All of this can be done within the SparkFun Arduino Library. We’ve also made sure to configure the UART pin grouping on the breakout to an industry standard to insure that it easily connects to a Serial Basic.
The SparkFun ZOE-M8Q GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZOE-M8Q. This reduces the time-to-first fix from a cold start (~30s) to a hot start (~1s). The battery will maintain RTC and GNSS orbit data without being connected to power for up to five hours. Since the ZOE-M8Q is a tiny GPS receiver and to minimize its footprint, we’ve added a U.FL connector to allow the use of both large standard ceramic antennas as well as very small chip scale antennas.
Note: The I2C address of the ZOE-M8Q is 0x42 and is software configurable. A multiplexer/Mux is required to communicate to multiple ZOE-M8Q sensors on a single bus. If you need to use more than one ZOE-M8Q sensor consider using the Qwiic Mux Breakout.
The ZOE-M8Q GPS Breakout can also be automatically detected, scanned, configured, and logged using the OpenLog Artemis datalogger system. No programming, soldering, or setup required!
