About this item

The SparkFun GPS-RTK-SMA is a high-precision GPS board built around the powerful u-blox ZED-F9P module, capable of achieving centimeter-level 3D accuracy using RTK technology. Designed for both rover and base station operations, it enables ultra-precise positioning for advanced navigation applications. The board supports multiple satellite constellations and dual-frequency bands (L1C/A, L2C) for enhanced performance. It offers seamless integration via SparkFun’s Qwiic system or standard 0.1" headers. With flexible configuration options, geofencing, and multiple communication interfaces—including USB-C, UART, I2C, and SPI—the GPS-RTK-SMA is ideal for high-end GNSS projects requiring accuracy, reliability, and easy connectivity.
