SparkFun GPS-RTK2 Board - ZED-F9P (Qwiic)
The SparkFun GPS-RTK2 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 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.
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 connnectors or broken out pins), and SPI.
We’ve also written an extensive Arduino library for u-blox modules to make reading and controlling
the GPS-RTK2 over our Qwiic Connect System easy. Leave NMEA behind! Start using a much
lighter weight binary interface and give your microcontroller (and its one serial port) a break. The
SparkFun Arduino library shows how to read latitude, longitude, even heading and speed over I2C
without the need for constant serial polling.
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.
