@dbrgn @emilygorcenski It is an evaluation board from Sparkfun with Ublox Zed-f9p onboard. I made some additions of hc-06 serial bluetooth and lipo power management. Using it with ublox patch antenna. Mostly connected to panasonic toughbook gfz-g1 with #qgis. Sadly my favorite editing software Merkaartor doesn't parse high precision #nmea settings. So I record, export geojson and import it to ID to retrace. Inefficient but works for now...
