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.\nThe Ultimate GNSS Carrier for Your SBC\nDesigned for maximum flexibility, the GNSS Flex pHAT serves as the bridge between your SBC and your chosen GNSS module.\n\n\nBroad 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.\n\nSolder-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.\n\nModular Flex Headers: The standardized 2x10-pin male headers enable easy attachment, swapping, or upgrading of your GNSS Flex module at any time.\n\nFull Interface Access: The pHAT breaks out all potential interfaces from the attached module, including up to four UARTs, I²C, USB, and critical timing signals. \n\nChoose Your GNSS Module\nPlease 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.\nThis 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.\n\nThe GNSS Flex Module has one to two U.FL connectors for an external antenna.\nFor 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.\n\nThis 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, 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 utilize any of the other interfaces.\n\n\n\n\n\nDoes not include:\n\n\nGNSS Flex Module\n\nSparkPNT GNSS Flex Module - mosaic-X5\nSparkPNT GNSS Flex Module - ZED-X20P & IM19 IMU\nSparkPNT GNSS Flex Module - ZED-X20P\nSparkPNT GNSS Flex Module - LG290P & IM19 IMU\nSparkPNT GNSS Flex Module - LG290P\nSparkPNT GNSS Flex Module - LG580P\nSparkPNT GNSS Flex Module - DAN-F10N\n\n\nRaspberry Pi Hat Hardware\nU.FL to U.FL Mini Coax Cable\nGNSS Antenna\nRaspberry Pi (or similar single-board computer)\n\n\n\n\n\n\n\n\n\nSee our full lineup of high-precision GNSS enclosed devices and development boards.\n\n\nLEARN MORE\n\n\n\n\n\n\n\n\n\n\n\n\nThis product features Qwiic Connectors.\n\n\nLEARN MORE\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nFeatures & Specs\n \n\n\n40-pin socket for Raspberry Pi header (or similar SBC)\n\n40-pin header for GNSS Flex modules\n\nTwo 2x20-pin, 2mm-pitch male headers\n\nPower\n\n3.3V\nBackup power\nUSB bus detect (not a power source)\n\n\nUSB data\nUART (x4)\nSD card\nI2C bus\nPPS signal (x2)\nLED indicators (x2)\nEvent indicators (x2)\n\n\n\n\nUSB-C connector\n\nInterfaces directly with GNSS Flex Module\n\n\nAntenna bridge\n\nU.FL connector\nSMA connector\n\n\nµSD card socket\nQwiic connector\nIndicator LEDs\n\nPWR (Red)\n\nPPS (Yellow)\n\nRTK (White)\n\nPVT (Blue)\n\n\n\nTwenty-four jumpers\n\nRaspberry Pi GPIO isolation (x16)\nLED power isolation (x4)\nI2C pull-up resistors (x4)\n\n\n\n\n\n\n\n\nDocumentation\n \n\nSchematic\nKiCad Files\nBoard Dimensions\nSTEP File\nHookup Guide\nBuilding a GNSS System\nQwiic Info Page\nGitHub Hardware Repo\n\n\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":136,"title":"Default Title","sku":"SF-GPS-28137","mpn":"GPS-28137","price":42.0,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
