SparkFun GNSS Flex pHAT

Easily add high-precision GNSS to your Raspberry Pi or favourite single-board computer with the SparkFun GNSS Flex pHAT. This carrier board is the heart of our SparkPNT Flex ecosystem, providing a solder-free, plug-and-play solution for connecting our powerful GNSS Flex modules. It's the most straightforward way to create a compact, modular, and powerful navigation system for your project.

The Ultimate GNSS Carrier for Your SBC

Designed for maximum flexibility, the GNSS Flex pHAT serves as the bridge between your SBC and your chosen GNSS module.

• Broad SBC Compatibility: The 40-pin header is designed for a direct connection to a Raspberry Pi, NVIDIA Jetson Nano, Google Coral, or other compatible single-board computers.
• Solder-Free Installation: With pre-soldered headers, there's no soldering required. Simply stack the pHAT on your SBC, attach a module, and you're ready to go.
• Modular Flex Headers: The standardized 2x10-pin male headers enable easy attachment, swapping, or upgrading of your GNSS Flex module at any time.
• Full Interface Access: The pHAT breaks out all potential interfaces from the attached module, including up to four UARTs, I²C, USB, and critical timing signals. 

Choose Your GNSS Module

Please note that this is a carrier board only and does not include a GNSS module. This allows you to select the perfect engine for your application's needs, from meter-level positioning for urban environments to all-band RTK with heading for autonomous navigation. Explore our comprehensive lineup of SparkPNT GNSS Flex Modules to complete your setup.

This product may require an external antenna for operation, depending on the GNSS Receiver. Users have a few options for connecting an external GNSS antenna to their GNSS receiver.

• The GNSS Flex Module has one to two U.FL connectors for an external antenna.
• For a sturdier connection, an SMA connector is available on this 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 catalogue. By default, we use the Raspberry Pi's primary serial bus (i.e. TX: GPIO14/Pin 8; RX: GPIO15/Pin 9) to communicate with the GNSS receiver of the SparkPNT GNSS Flex module. However, users can also utilise any of the other interfaces.
