Achieve centimeter-level positioning with the next generation of high-precision GNSS using the SparkFun ZED-X20P GNSS Flex pHAT. This module features the latest u-blox X20 engine, the powerful successor to the popular F9 engine, making it the ideal choice for demanding navigation and control applications.

The GNSS Flex pHAT acts as the bridge between your Raspberry Pi and the modular SparkPNT ecosystem. It mounts securely via an extended 40-pin header and connects to the included GNSS module using standardized 2x10-pin headers, making it simple to swap modules for repairs or future upgrades.

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.

X20P Marks the Spot

At the core of the Module on the pHAT is the u-blox ZED-X20P, a professional-grade, all-band GNSS receiver that delivers centimeter-level accuracy. It concurrently processes signals from all major constellations (GPS, Galileo, BeiDou, etc.) across all frequency bands, including L-band, providing incredibly fast and reliable fixes for control applications like UAVs, guidance systems, and auto-steering.

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.

This product requires an external antenna and a GNSS Flex carrier board. Users have a few options for connecting an external GNSS antenna to their GNSS receiver.

The GNSS Flex module has a U.FL connector for an external antenna.
For a sturdier connection, an SMA connector is available on the SparkFun GNSS Flex pHAT that is bridged to a U.FL connector. Users simply need to jumper the U.FL connectors on both the SparkPNT GNSS Flex module and SparkFun GNSS Flex pHAT with a short U.FL cable.

This pHAT also requires a Raspberry Pi (or similar single-board computer). Users can find Raspberry Pi and NVIDIA single-board computers in our catalog. By default, Sparkfun utilize the Raspberry Pi's primary serial bus (i.e., TX: GPIO14/Pin 8; RX: GPIO15/Pin 9) for communication with the GNSS receiver of our SparkPNT GNSS Flex modules. However, users can also utilize any of the other interfaces.

*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.
