GPS-RTK-SMA ZED-F9P Breakout

The SparkFun GPS-RTK-SMA breakout integrates a powerful GNSS module from u-blox onto a development-friendly board with SMA connectors and Qwiic support, offering real-time kinematic (RTK) positioning down to centimeter-level accuracy. It supports concurrent reception of GPS, GLONASS, Galileo, and BeiDou with dual-frequency reception (L1/L2) for improved resistance to multipath interference and faster convergence.

Unlike the U.FL version, this breakout uses SMA antenna connectors for improved RF robustness, making it suitable for field deployments, research, robotics, and surveying where ruggedized connections are preferred. With support for both I²C (via Qwiic) and UART/SPI interfaces, plus USB-C for configuration through u-center or GNSS data access, the board can function as a rover or base station depending on the application.
