SparkFun GNSS Timing Breakout - ZED-F9T (Qwiic)

The SparkFun GNSS Timing Breakout is a specialized tool designed for applications where time is just as critical as position. Featuring the u-blox ZED-F9T GNSS receiver this board offers an impressive five nanoseconds of timing accuracy under clear skies without requiring any external GNSS correction data. Whether you are maximizing the efficiency of a 5G IoT network synchronizing a distributed sensor grid or building a high-precision NTP server this breakout provides the ultra-accurate time reference you need.Multi-Band ReliabilityThe ZED-F9T is a top-of-the-line multi-band module that supports L1 L2 and E5b bands across all major constellations (GPS GLONASS Galileo and BeiDou). By tracking multiple bands concurrently the ZED-F9T ensures extreme versatility and timing stability even if it loses lock with one or more specific constellations.Comprehensive ConnectivityWe designed this breakout to be a complete GNSS development tool even borrowing the form factor of our popular ZED-F9P Qwiic GPS-RTK-SMA Breakout to give you every connection you need:SMA Connectors: Includes three SMA connectors (one for the antenna and two dedicated for timing pulse signals) allowing for secure low-loss connections to external equipment.USB-C & Qwiic: Features a modern USB-C connector for primary power and communication plus two Qwiic connectors for easy solder-free I2C integration with the rest of your system.Full Access: For advanced users we have exposed a set of PTH pins enabling direct access to most of the ZED-F9T's pinout.Fast AcquisitionTo ensure your system is up and running quickly the breakout includes an onboard rechargeable backup battery. This powers the module's internal Real-Time Clock (RTC) reducing Time-To-First-Fix from a cold start (~24 seconds) to a hot start (~2 seconds).
