GPS-RTK2 Board ZED-F9P: Genuine SparkFun Hardware
This is a genuine SparkFun module — “SparkFun” and “GPS-RTK2” are clearly printed on the board itself, alongside the u-blox ZED-F9P module label. It’s SparkFun’s flagship high-precision GNSS breakout, built around a multi-band receiver that tracks GPS, GLONASS, Galileo, and BeiDou simultaneously on both L1 and L2 frequencies — the dual-band tracking is what gets RTK positioning down to roughly 10mm in three dimensions, well beyond what a typical single-band consumer GPS module can achieve.
The same board works as either an RTK rover (receiving correction data to achieve high-precision fixes) or a fixed base station (using Survey-In mode to determine its own position and broadcast RTCM 3.x corrections to nearby rovers) — genuinely useful for building your own base/rover RTK pair rather than needing to buy two different products. Dual Qwiic connectors mean no soldering is required to wire it into a compatible project, while five simultaneous communication interfaces (USB-C, dual UART, I²C, and SPI) keep it flexible for drones, robotics, and embedded systems alike. An onboard rechargeable backup battery keeps satellite almanac data warm for roughly two weeks, meaningfully shortening time-to-first-fix on repeat power-ups.
