## Overview

The SparkFun GNSS Timing Breakout-ZED-F9T is a cutting-edge multi-band GNSS receiver delivering up to 5 nanosecond timing accuracy without external corrections. Supporting GPS, GLONASS, Galileo, and BeiDou constellations concurrently, it ensures robust and reliable positioning and timing. Designed for professional IoT and 5G applications, it features rapid fix acquisition, dual Qwiic connectors for easy I2C integration, USB-C power, and SMA antenna ports. This compact breakout board accelerates development with SparkFun’s ecosystem but requires separate purchase of antenna, cables, and microcontroller.

## Description

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).The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Review: MOSI/MISO pins double up as the UART TX/RX pins - This took a long time to debug, but once I figured the UART pins for serial communication for Raspberry Pi were doubled up on on the SPI pins, it all worked fine. Used a Salaea to debug.
Review: No access to firmware updates or changelogs - U-Blox for some reason does not provide access to firmware updates and other resources for ZED-F9T, unless you're a big client with an NDA. They don't even respond to emails or support tickets. Not even a reply indicating that they won't provide the firmware downloads. They just close tickets without responding. This means that not all the functionality which are in the docs do work with these SparkFun modules, which ship with an older firmware version. I ended up buying some boards from ArduSimple, which even with shipping from Europe to Seattle ended up being cheaper and much more useful.
