Board Alignment

The GNSS Flex system is a modular ecosystem designed around two 2x10-pin, 2mm pitch headers, so boards are pin-compatible for upgrades and easily swapped for repairs. Users simply, stack a SparkPNT GNSS Flex module onto the headers of its associated carrier board. The alignment of these boards is annotated with a triangle in the corner of the mating area.

External Antenna

In order to receive GNSS signals, users will need a compatible antenna. For the best performance, we recommend an active, L1/L2/L5/L6 GNSS antenna.

• External antennas can be connected through the U.FL connector on the GNSS Flex board.
• For a sturdier connection, there is a signal pass-through between the U.FL and SMA antenna connectors of the Flex carrier boards. Users can to bridge the U.FL connections of the boards to utilize the SMA connector for a GNSS antenna.
