This top-tier PNT add-on for the Raspberry Pi combines our versatile pHAT carrier with the industrial-grade Septentrio mosaic-X5, a compact and powerful RTK receiver engineered for the most demanding applications in autonomous systems, industrial automation, and scientific research.\nThe 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.\n\n\nRaspberry Pi Connectivity: Standard 40-pin GPIO header for a direct, secure connection.\n\nNative USB Access: A dedicated USB-C port connects directly to the mosaic-X5's USB hardware for high-speed data access to its web server.\n\nmicroSD Card Slot: Ideal for logging data on position, velocity, and time.\nMounting Hardware Included: Comes with the necessary standoffs, screws, and an extended header for a clean, stable setup.\n\n\nSurvey-Grade RTK Precision\nAt the heart of this pHAT is the Septentrio mosaic-X5, a multi-band, multi-constellation receiver known for its best-in-class reliability and performance.\n\n\nMillimeter-Level Accuracy: Delivers an astonishing 6mm horizontal and 1cm vertical accuracy with RTK, plus timing precision down to five nanoseconds.\n\nAIM+ Interference Mitigation: Features Septentrio's unique AIM+ technology, a powerful anti-jamming and anti-spoofing system that ensures unparalleled robustness and reliability in noisy RF environments.\n\nMulti-Band & Multi-Constellation: Tracks all signals from all major constellations (GPS, GLONASS, Galileo, BeiDou, NavIC) for maximum satellite availability and fast, reliable fixes.\n\nIntuitive Configuration & Advanced Control\nThe mosaic-X5 offers a sophisticated yet user-friendly experience for control and configuration, setting it apart from typical receivers.\n\n\nBrowser-Based Interface: Access the powerful, built-in web server from any browser via the USB or dedicated Ethernet connection for intuitive setup, monitoring, and data logging.\n\nCommand-Line Interface: For power users and automated testing, a full Command-Line Interface (CLI) is also available for deep configuration and control.\n\n\n\nThis product requires an external antenna. Users have a few options for connecting an external GNSS antenna to their GNSS receiver.\n\nThe GNSS Flex module has a U.FL connector for an external antenna.\nFor 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.\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\n\nProduct includes:\n\n\nx1 - SparkFun GNSS Flex pHAT\n\nx1 - SparkPNT GNSS Flex Module - mosaic-X5\n\nx1 - Tall GPIO Female Headers - 2x20 Pin\n\nx1 - U.FL to U.FL Cable - 50mm\n\nx4 - Aluminum Hex Standoff (Thread: M2.5-0.45; Length: 16mm)\n\nx8 - Phillips Machine Screw (Thread: M2.5-0.45x8mm)\n\n\n\nDoes not include:\n\n\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\nSee our full lineup of products powered by Septentrio GNSS modules.\n\n\nLEARN MORE\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nFeatures & Specs\n \n\nGNSS Flex pHAT:\n\n40-pin socket for Raspberry Pi header\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 w/ 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\nmosaic-X5 GNSS Flex Module:\n\nSeptentrio mosaic-X5 GNSS Receiver\n\nGNSS Constellations:\n\nGPS (USA)\nGLONASS (Russia)\nGalileo (EU)\nBDS (China)\nQZSS (Japan)\nNavIC (India)\n\n\nSBAS Systems:\n\nWAAS (USA)\nSDCM (Russia)\nEGNOS (EU)\nMSAS (Japan)\nGAGAN (India)\n\n\n\n\nThree 2x20-pin, 2mm-pitch female headers\n\n40-pin socket for GNSS Flex system\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\n20-pin socket for mosaic-X5 Ethernet PHY\n\n\nU.FL Connector:\n\nGNSS Antenna (Active, Multi-band)\n\n\n\n\n\nmosaic-X5 GNSS Receiver:\n\nVoltage Range: 3.135 to 3.465V\n\nMax current: 500mA\n\n\nRTK Accuracy\n\nHorizontal: 0.6cm (±0.5ppm)\n\nVertical: 1cm (±1ppm)\n\n\n\nChannels: 448 (simultaneous tracking)\n\nGNSS Frequency Bands:\n\nGPS: L1C/A, L1PY, L2C, L2P, L5\n\nGLONASS: L1CA, L2CA, L2P, L3 CDMA\n\nBeidou: B1I, B1C, B2a, B2b, B2I, B3\n\nGalileo: E1, E5a, E5b, E5 AltBoc, E6\n\nQZSS: L1C/A, L1 C/B, L2C, L5\n\nNavIC: L5\n\nSBAS: Egnos, WAAS, GAGAN, MSAS, SDCM (L1, L5)\nL-band\n\n\nTime to Fix\n\nCold Start: < 45s\nWarm: < 20s\nReacquisition: 1s\n\n\nTiming Precision: 5ns\nUpdate Rate: 100Hz\nLatency: < 10ms\n\nVANT Voltage Range: 3.0 to 5.0V\n\nMax current: 150mA\n\n\nInterfaces:\n\nUART (x4)\nEthernet\nUSB device (2.0, HS)\nSDIO (mass storage)\nGPIO user programmable (x2)\nEvent markers (x2)\nConfigurable PPS out\n\n\n\n\n\n\n\n\nDocumentation\n \n\nDesign Files\n\nGNSS Flex pHAT\n\nSchematic\nKiCad Files\nBoard Dimensions\nSTEP File\n\n\nmosaic-X5 Flex Module\n\nSchematic\nKiCad Files\nBoard Dimensions\nSTEP File\n\n\n\n\n\nHookup Guide\n\nSoftware: RxTools\n\nCorrection Service: Agnostic Corrections\n\n\n\nComponent Datasheets:\n\n\nmosaic-X5 Datasheet\n\nmosaic-X5 Brochure\nFirmware Manual (v4.15.0)\n\n\nSeptentrio's GNSS Modules\nmosaic-X5 Product Page\n\n\nBuilding a GNSS System\nQwiic Info Page\nGitHub Hardware Repositories:\n\nGNSS Flex pHAT\nGNSS Flex Modules\n\n\n\n\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":139,"title":"Default Title","sku":"SF-GPS-28766","mpn":"GPS-28766","price":1200.0,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":9,"option1":"Default Title"}]}
