{"title":"NEO-D9S GNSS Correction Data Receiver with Qwiic","handle":"sparkfun-gnss-correction-data-receiver-neo-d9s-qwiic","url":"/products/sparkfun-gnss-correction-data-receiver-neo-d9s-qwiic","description":"This NEO-D9S breakout is an L-Band satellite correction data receiver designed to feed correction streams to a compatible multi-band, high-precision GNSS receiver such as the u-blox ZED-F9P. With a clear view of the sky, especially to the south, it can decode L-Band correction broadcasts and help a suitable GNSS system achieve centimetre-level positioning without a separate RTK or NTRIP correction source.The board includes USB-C for configuration from a computer using u-blox u-center, plus two Qwiic connectors for quick I2C connection to development boards. It is also supported by the SparkFun u-blox GNSS Arduino Library, with example code available for the NEO-D9S and for using the NEO-D9S with a ZED-F9P.An integrated SMA connector provides a secure connection to a suitable L-Band antenna, and power, I2C, UART1, UART2 and SPI are also broken out to 0.1\" spaced PTH pins. Please note that this product requires a suitable L-Band antenna.From 10 March 2025, the u-blox PointPerfect L-Band correction service for this receiver is currently only available in the USA's 48 contiguous states, with the EU L-Band service suspended from that date.Features:USB: 1x USB Type C ConnectorQwiic: 2x Qwiic ConnectorsAntenna connector: Integrated SMA connector for use with L-Band antenna of your choiceReception: Concurrent reception with L-Band SatellitePower LED: Power LEDUSB Shield jumper: USB ShieldPower jumper: Power3v3 jumper: 3v3 (for UART2 Port)I2C Pull-Up Resistors jumper: I2C Pull-Up ResistorsSPI jumper: SPIProtocols: Supports UBX protocols over UART or I2C interfacesSpecifications:Default I2C Address: 0x43Receives L-Band: 1525 MHz to 1559 MHzTime to First Frame: <10s @ 2400bpsUser Data Rates: 600, 1200, 2400, 4800 baudDynamics: +/- 2g acceleration for all data rates (600 bit/s, 1200 bit/s, 2400 bit/s, 4800 bit/s)Velocity: Up to and including 300 km/hVoltage: 5V or 3.3V but all logic is 3.3VCurrent Consumption (Acquisition & Tracking) Peak: 130mACurrent Consumption (Acquisition & Tracking) Average: 35mABoard Dimensions: 1.70\" x 1.70\" (43.2mm x 43.2mm)The Qwiic connectors use the common 1mm pitch, 4-pin JST format, making this board easy to add to Qwiic-based prototypes without soldering.","vendor":"SparkFun","product_type":"GNSS Receiver","in_stock":true,"options":[],"variants":[{"id":15769,"title":"Default Title","sku":"SF-GPS-19390","mpn":"GPS-19390","price":117.9,"on_sale":false,"in_stock":true,"available_quantity":46}]}
