The SparkFun GNSS Receiver breakout uses the u-blox SAM-M8Q, a compact, high-performance satellite navigation module for reliable and accurate positioning in embedded and IoT applications. It tracks GPS, GLONASS, Galileo and QZSS and supports the SBAS systems WAAS, EGNOS, MSAS and GAGAN.
Two 4-pin JST-SH Qwiic connectors allow easy I2C integration with other Qwiic boards, and a USB-C connector gives power and configuration.
The interfaces are I2C (Qwiic), UART and USB-C, at 3.3 V logic. The board measures 25.4 mm by 25.4 mm (1.00 by 1.00 inch) and has four holes compatible with 4-40 screws. A PPS signal is available for timing and synchronisation.
For a first test, connect the board over USB-C and open it in u-blox's u-center software to watch the satellites and configure the output. For the best signal, use it outdoors with a clear view of the sky and keep it away from switching regulators and radio transmitters.
Makers using SparkFun or other Qwiic boards, and developers who want an easy way to get location and time into a prototype.
With Qwiic, plug the board into a compatible controller with a Qwiic cable and read the data with a library that supports the u-blox I2C protocol. With USB-C, the board acts as a serial device for use with a computer. Keep the on-board antenna facing the sky and clear of metal, and avoid placing it next to batteries or motor drivers.
