SparkFun GPS-19984 RTK Facet

SparkFun GPS-19984 RTK Facet is designed for high-precision geolocation and surveying. RTK Facet is one of the fastest ways to take centimeter-grade measurements. Under the hood of the RTK Facet is an ESP32 WROOM. This ESP32 WROOM is connected to a ZED-F9P as well as some peripheral hardware (LiPo fuel gauge, and microSD). Under the dome of RTK Facet is a surveyor-grade L1/L2 antenna and the same elements are found within the GNSS Multi-Band L1/L2 surveying antenna. The RTK Facet works with common GIS software including SW Maps, SurvPC, Field Genius, and any GIS software that supports NMEA over Bluetooth®. The GPS-19984 RTK Facet features a GNSS receiver ZED-F9P and Bluetooth® transceiver ESP32 WROOM.
