SparkFun GNSS Timing Breakout - ZED-F9T (Qwiic) - ของแท้จาก SparkFun, USA

The SparkFun GNSS Timing Breakout offers a unique entry into SparkFun's geospatial catalog featuring the ZED-F9T GNSS receiver from u-blox. The ZED-F9T provides up to five nanosecond timing accuracy under clear skies with no external GNSS correction making it perfect for applications where timing accuracy is imperative. Need an extremely accurate time reference to maximize the efficiency of your IoT network of 5G devices? The ZED-F9T GNSS Timing Breakout could be the perfect solution.

The ZED-F9T is a multi-band GNSS module that supports L1/L2/E5b bands and operates on all major constellations (GPS, GLONASS, Galileo and BeiDou) concurrently making it extremely versatile and able to retain its timing precision even the module loses lock with one or more of the visible constellations.

This breakout shares a similar design as the SparkFun GPS-RTK-SMA Breakout to create a small but comprehensive development tool for the ZED-F9T. The design includes a USB-C connector for primary power and communication, two Qwiic connectors for communicating over I2C using the SparkFun Qwiic system, three SMA connectors for the antenna and timing pulse signals as well as a host of PTH pins allowing direct interaction with most of the ZED-F9T's pinout. The GNSS Timing Breakout also includes an on-board rechargeable backup battery that provides power to the RTC on the ZED-F9T. This reduces the time-to-first fix from a cold start (~24s) to a hot start (~2s).
