--   This SparkPNT GNSS Flex module features the u-blox DAN-F10N GNSS module with u-blox's dual-band GNSS technology for the L1/L5 frequency bands. Their proprietary dual-band multipath mitigation technology enables the u-blox F10 GNSS engine to isolate the best signals from the L1 and L5 bands; delivering a solid meter-level position accuracy in challenging urban environments. Additionally, the DAN-F10N module's robust SAW-LNA-SAW RF architecture with an additional notch filter (LTE B13) on the L1 RF path ensures the best possible out-of-band interference mitigation from nearby cellular modems.
+-   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. For the DAN-F10N GNSS module, these pins will break out the UART (x1) interface, along with the PPS, event, and reset signals using a standardized pinout.

 	The DAN-F10N GNSS module on this board comes with a 20 x 20 x 8 mm, integrated, Right Hand Circular Polarized (RHCP), L1/L5 dual-band patch antenna that offers the best compromise between size and performance. The patch antenna's wide beamwidth provides flexibility in the device's orientation; while alternatively, the module also has an antenna switch function to give users the option to utilize an external dual-band antenna, further increasing its utility.

--	This SparkPNT GNSS Flex module features the [Septentrio mosaic-X5](https://www.septentrio.com/en/products/gnss-receivers/gnss-receiver-modules/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**](https://learn.sparkfun.com/tutorials/813) (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](https://www.septentrio.com/en/learn-more/advanced-positioning-technology/aim-jamming-protection) 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 an third 2x10 pin, 2mm pitch female header. To guide users through the configuration options, Septentrio provides dozens of [video tutorials](https://www.youtube.com/@SeptentrioGNSS/videos) about the web interface.
