SparkFun GPS-16481 GPS-RTK Breakout - ZED-F9P, SMA Antenna (Qwiic)

The SparkFun GPS-16481 is a u-blox ZED-F9P RTK breakout with an SMA antenna connector. It can work as a centimetre-level rover or as a base station for drones, ground robots and survey rigs. This is the SMA version; the GPS-15136 board uses a U.FL connector.

Key features

• Dual-band L1C/A and L2C reception across GPS, GLONASS, Galileo and BeiDou
• RTK fixes down to 0.010 m horizontal, with updates at up to 20 Hz
• Works as a rover or as a base station
• USB-C, UART, I2C, SPI and two Qwiic ports to connect a microcontroller, companion computer or autopilot
• SMA jack takes a full-size survey or helical antenna with a secure screw-on fit
