u-Blox ZED and xPico 200 series WiFi
The 3DR ZED-F9 GPS is a high-performance device capable of using all constellations simultaneously, including the more precise L2 band, making it the most precise GPS available today.
ZED-F9 GPS from 3DR also features a proprietary RF stage, which delivers high gain and high noise immunity compared to passive antennas. It also uses less space and weight than most active antenna counterparts and eliminates signal loss caused by u.Fl/SMA antenna connectors and long cables.
This module includes an xPico 200 series module, the XPC240, which provides dual band WiFi telemetry capabilities (2.4GHz and 5GHz). The XPC host application provides a simple interface for configuring and managing the module. For more information, please visit the xPico resources site.
The board also includes our M00073 RM3100 compass module, which provides survey-grade heading.
