The SparkFun mosaic-X5 GNSS Flex pHAT is a development platform for the SparkFun GNSS Flex system. Designed to interface with a Raspberry Pi or comparable single-board computers via a 40-pin header, it acts as a carrier board for the SparkPNT mosaic-X5 GNSS Flex Module. The GNSS Flex system employs a modular design based on two 2x10-pin, 2mm pitch headers, ensuring pin compatibility across boards for simplified upgrades and repairs.

With the SparkPNT mosaic-X5 GNSS Flex module, these headers break out the UART (x4), USB, and SD card interfaces of the mosaic-X5 GNSS receiver and the PPS and event signals. Meanwhile, on the SparkFun GNSS Flex pHAT, the headers are connected to the USB-C connector, µSD card slot, and 40-pin header. This kit also includes the extension header, standoffs, and screws necessary to mount a pHAT on top of a Raspberry Pi.

The SparkPNT GNSS Flex module features the Septentrio mosaic-X5, a compact, ultra-low power, multi-band, multi-constellation, high-precision GNSS receiver. The receiver supports the GPS (USA), GLONASS (Russia), Beidou (China), Galileo (Europe), and NavIC (India) constellations, including regional systems (i.e., SBAS and QZSS). With its Real Time Kinematics (RTK) capabilities, the module can achieve a horizontal accuracy of 6mm (~0.25in), vertical accuracy of 1cm (~0.4in) using RTK, and timing precision of 5ns (5 billionths of a second). It also features Septentrio's unique AIM+ technology for interference mitigation and anti-spoofing, ensuring best-in-class reliability and scalable position accuracy.

The mosaic-X5 is a sophisticated module with an internal web server that can be utilized with any web browser. On the GNSS Flex module, the web server is accessed through either the USB data pins from the standard GNSS Flex headers or the Ethernet PHY of the mosaic-X5, which is broken out on a third 2x10-pin, 2mm pitch female header.

For the users who prefer a command-line interface, Septentrio has you covered. Users can still control and configure the mosaic-X5 module through a CLI, which is helpful for scenarios such as production line testing (in fact, that is how Sparkfun test this board) or remote access.
