This means the higher the accuracy the better! GPS Real Time Kinematics (RTK) has mastered dialing in the accuracy on their GPS modules to 25mm, and that's why Sparkfun 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 top-of-the-line module for high accuracy GNSS and GPS location solutions including RTK. With this board you will be able know where you (or any object) are within one inch! The NEO-M8P-2 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, Sparkfun still have broken out 0.1"-spaced pins in case you prefer to use a breadboard. We've even included a rechargable 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 (as opposed to the previous version of the module which is not able to produce RTCM data). The number of configuration options of the NEO-M8P-2 is incredible! Geofencing, variable I2C address, variable update rates, even the high precision RTK solution can be increased to 4Hz. The GPS-RTK even has four communications ports: USB (which enumerates as a COM port), UART (with 3.3V TTL), I2C (via the two Qwiic connnectors or broken out pins), and SPI. We've also written an [Arduino library for u-blox modules](https://github.com/sparkfun/SparkFun_Ublox_Arduino_Library) to make reading and controlling the GPS-RTK over our [Qwiic Connect System](https://www.sparkfun.com/qwiic) easy. *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.* [Get Started With the SparkFun GPS-RTK Board Guide](https://learn.sparkfun.com/tutorials/gps-rtk-hookup-guide) **Features** - Voltage: 5V or 3.3V but all logic is 3.3V - Current: ~35mA (varies with constellations and tracking state) - Time to First Fix: 29s (cold), 1s (hot) - Max Navigation Rate: - PVT (basic location over UBX binary protocol) - 10Hz - RTK - 5Hz - Moving Baseline RTK - 4Hz - Raw - 10Hz - Horizontal Position Accuracy: - 2.5m without RTK - 0.025m with RTK - 2x Qwiic Connectors - Weight: 6.3g - Dimensions: 40.6mm x 33mm (1.6in x 1.3in) **Documents** - [Schematic](https://core-electronics.com.au/attachments/localcontent/Qwiic_GPS-RTK_-_ublox_NEO-M8P_8452134f0da.pdf) - [Eagle Files](https://core-electronics.com.au/attachments/localcontent/Qwiic_GPS-RTK_-_ublox_NEO-M8P_2164815a0d4.zip) - [Hookup Guide](https://learn.sparkfun.com/tutorials/gps-rtk-hookup-guide) - [What is GPS RTK?](https://learn.sparkfun.com/tutorials/what-is-gps-rtk) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/NEO-M8P_DataSheet__UBX-15016656__19497f5fbbc.pdf) (NEO-M8P-2) - [Product Summary](https://core-electronics.com.au/attachments/localcontent/NEO-M8P_ProductSummary__UBX-15015836__321798c2930.pdf) (NEO-M8P) - [Hardware Integration Manual](https://core-electronics.com.au/attachments/localcontent/NEO-M8P_HardwareIntegrationManual__UBX-15028081__12175b2dff9.pdf) (NEO-M8P) - [Receiver Description](https://core-electronics.com.au/attachments/localcontent/u-blox8-M8_ReceiverDescrProtSpec__UBX-13003221__Public_83868735efc.pdf) (u-blox 8 / M8) - [u-blox ECCN](https://core-electronics.com.au/attachments/localcontent/Ublox_ECCN_28495c374c6.pdf) - [Example RTCM Output](https://cdn.sparkfun.com/assets/5/3/8/5/7/Example_RTCM_Binary_Output.txt) - [Arduino Library](https://github.com/sparkfun/SparkFun_Ublox_Arduino_Library) - [GitHub](https://github.com/sparkfun/Qwiic_GPS-RTK) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/1/5/15005-sparkfun_gps-rtk__qwiic__-_neo-m8p-2-00.jpg)
