Based on the SparkFun GPS-RTK2 designs, the SparkFun GPS-RTK-SMA raises the bar for high-precision GPS and is the latest in a line of powerful RTK boards featuring the ZED-F9P module from u-blox. The ZED-F9P is a top-of-the-line module for high accuracy GNSS and GPS location solutions including RTK that is capable of 10mm, three-dimensional accuracy. With this board, you will be able to know where your (or any object's) X, Y, and Z location is within roughly the width of your fingernail! The ZED-F9P is unique in that it is capable of both rover and base station operations. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.
We've included a rechargeable backup battery to keep the latest module configuration and satellite data available for up to two weeks. This battery helps 'warm-start' the module decreasing the time-to-first-fix dramatically. This module features a survey-in mode allowing the module to become a base station and produce RTCM 3.x correction data. Based on your feedback, we switched out the u.FL connector and included an SMA connector in this version of the board.
The number of configuration options of the ZED-F9P is incredible! Geofencing, variable I2C address, variable update rates, even the high precision RTK solution can be increased to 20Hz. The GPS-RTK2 even has five communications ports which are all active simultaneously: USB-C (which enumerates as a COM port), UART1 (with 3.3V TTL), UART2 for RTCM reception (with 3.3V TTL), I2C (via the two Qwiic connectors or broken out pins), and SPI.
We've also written an extensive Arduino compatible library for u-blox modules to make reading and controlling the GPS-RTK-SMA over Qwiic easy. Note: Purchase antenna separately.

Spent a week trying the differing and dispersed documentation suggestions that I could find on the web and support forums, but ultimately established that no matter what i tweaked, cut, or downloaded, the I2C bus would eventually crash either during boot, setup, or a few GPS readings. And it stays down. Need to ground the reset pin or pull pwr, and then reboot & try setup cmds again, being ready to do it over and over again. Makes for a complicated system, as extra components are necessary, and consuming additional power. Unfortunately had done a lot of prep work anticipating that the I2C & qwiic connectors would do their job with an arduino. So far, can only use the GPS manually with the excellent U-center utility on a larger computer with usb. support. Searched for more complete and consistent specs and examples for wiring & commanding the other comm channels. None of the examples worked with my Arduinos. over the Qwicc connector I2C bus. Its the only I2C link that I've had any trouble with in 10 years. At some point, the device pulls one of the I2C lines low, blocking all comms until reset or pwr cycle.Update: Was eventually able to by lengthy experiments & watching a scope, create code that worked in ublox mode, and was stable for hours over the I2C bus. Limited success but at least with difficulty, it can be made to work with the newer faster Arduinos.

Very good capture performance and lock-time. Good for serious applications.
