{"title":"GNSS Flex pHAT with u-blox ZED-X20P","handle":"sparkfun-gnss-flex-phat-zed-x20p","url":"/products/sparkfun-gnss-flex-phat-zed-x20p","description":"Bring high-precision GNSS to a Raspberry Pi with this GNSS Flex pHAT and u-blox ZED-X20P receiver module. It is built for centimetre-level positioning in demanding navigation and control projects such as UAVs, guidance systems, auto-steering and high-speed robotics.The pHAT connects to a Raspberry Pi through an extended 40-pin header and links to the included GNSS Flex module using standardised 2x10-pin headers, so the receiver module can be swapped for repair or future upgrades. It also includes USB-C data access, Qwiic, microSD, status LEDs and both SMA and U.FL antenna options.An external GNSS antenna is required, along with a Raspberry Pi or similar single-board computer. By default, communication uses the Raspberry Pi primary serial bus: TX: GPIO14/Pin 8 and RX: GPIO15/Pin 9, although other interfaces can also be used.According to u-blox, support for Precise Point Positioning (PPP) and full L-band correction services is still under development and will be made available through a future firmware update.Features:Raspberry Pi Connectivity: Standard 40-pin GPIO header for a direct, secure connection.USB-C Port: Provides an alternative data interface to the GNSS module. (Read USB note)Versatile Antenna Connections: Equipped with both SMA and U.FL connectors to accommodate various antenna types.Mounting Hardware Included: Comes with the necessary standoffs, screws, and an extended header for a clean, stable setup.RTK & PPP Ready: Supports Real-time Kinematics (RTK), PPP-RTK, and Precise Point Positioning* for ultimate flexibility.L-Band Corrections: Natively supports L-band correction services*, eliminating the need for external receivers.High Update Rate: Ensures smooth and reliable operation in high-speed robotics and vehicle control systems.Uncompromising Security: Features multi-layered defenses including a Root of Trust, advanced jamming and spoofing detection, and Galileo OSNMA cryptographic authentication.ZED-X20P feature:
