SparkPNT GNSS Flex Modules are plug-in boards featuring different GNSS receivers. They are designed to be easily swapped for repairs and pin-compatible for upgrades. The boards have two 2x10-pin, 2mm pitch female headers connecting to carrier boards. Using a standardized pinout for the mosaic-X5 GNSS receiver, these pins break out the USB, UART (x4), and SD card interfaces and the PPS or event signals.

This 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.
