Sparkfun GPS-15005 Expansion card 1 pc(s) Compatible with: Arduino

With GPS, you know where you are, where you are going and how to get anywhere on Earth within 30 seconds. This means that the higher the accuracy, the better! GPS Real Time Kinematics (RTK) has mastered the dial-in to accuracy on their GPS modules on 25mm, so we had to put it on this board!
The Sparkfun GPS-RTK Board is a powerful breakout board for the NEO-M8P-2 module from u-blox. The NEO-M8P-2 is a highly accurate module for GNSS and GPS positioning solutions including RTK. With this board you will be able to know where you (or any other object) are within one centimeter! The NEO-M8P-2 is unique because it enables both rover and base station operation. By using our convenient Qwiic system, no soldering is required to connect it to the rest of your system. However, if you prefer to use a breadboard, we have broken out 0.1" intermediate pins.
We even have a rechargeable backup battery built in to keep the current module configuration and satellite data available for up to two weeks. This battery helps with the 'warm start' of the module and drastically shortens the time until the first repair. This module has a Survey-in mode that allows the module to become a base station and generate RTCM 3.x correction data (as opposed to the previous version of the module that cannot generate RTCM data).
The number of configuration options of the NEO-M8P-2 is unbelievable! Geofencing, variable I2C address, variable update rates, even the highly precise RTK solution can be increased to 4Hz. The GPS-RTK even has four communication ports: USB (which is listed as a COM port), UART (with 3.3V TTL), I2C (via the two Qwiic plugs or broken pins) and SPI.
