{"title":"LG290P Quadband GNSS RTK Breakout (Qwiic)","handle":"sparkfun-quadband-gnss-rtk-breakout-lg290p-qwiic","url":"/products/sparkfun-quadband-gnss-rtk-breakout-lg290p-qwiic","description":"Built around the Quectel LG290P, this compact RTK GNSS breakout is designed for high-precision positioning projects that need quad-band, multi-constellation reception. It follows the same board dimensions, pin layout and connectors as SparkFun’s GPS-RTK-SMA Breakout - ZED-F9P (Qwiic), making it a familiar upgrade path.The LG290P can receive L1, L2, L5 and L6/E6 signals from GPS, GLONASS, Galileo, BDS, QZSS and NavIC, with support for SBAS, RTCM and RTK corrections. PPP services are listed by the module but are marked as under development, and corrections for some PPP services may not be implemented yet.Three UART ports are broken out via USB-C through a CH342 USB-serial converter, a 4-pin locking JST connector and a BlueSMiRF 6-pin header. Although the hardware lists UART, SPI and I2C options, the module currently supports only UART; SPI and I2C features are under development.It is suited to intelligent robots, UAVs, precision agriculture, mining, surveying and autonomous navigation, particularly where interference handling matters thanks to the built-in NIC anti-jamming unit.Features:GNSS module: Quectel LG290P quad-band, GNSS moduleGeneral feature: High-precision GNSS moduleConcurrent signal reception: 5 + QZSSFrequency bands: L1, L2, L5, E6 frequency bandsGNSS constellation: GPS (USA)GNSS constellation: GLONASS (Russia)GNSS constellation: Galileo (EU)GNSS constellation: BDS (China)GNSS constellation: QZSS (Japan)GNSS constellation: NavIC (India)SBAS system: WAAS (USA)SBAS system: SDCM (Russia)SBAS system: EGNOS (EU)SBAS system: BDSBAS (China)SBAS system: MSAS (Japan)SBAS system: GAGAN (India)Anti-jamming: Built-in NIC anti-jamming unitMounting: Four mounting holesMounting compatibility: 4-40 screw compatibleBackup power: Backup batterySpecifications:Breakout board dimensions: 1.70\" x 1.70\" (43.2mm x 43.2mm)PTH pins: 24 PTH PinsQwiic connector: 4-pin JST Qwiic connector* (x2)UART interfaces: UART interfaces (x3)USB connector: USB-C connectorBlueSMiRF/Serial-to-UART header: 6 PTH pins (BlueSMiRF/Serial-to-UART)Locking JST connector: 4-pin locking JST connectorPWR LED: Red 3.3V power indicatorPPS LED: Yellow Pulse-Per-Second indicatorRTK LED: White RTK correction indicatorSupply Voltage: 3.15–3.45VCurrent Consumption - Normal Operation Acquisition: 91mA (300.3mW) (Acquisition)Current Consumption - Normal Operation Tracking: 91mA (300.3mW) (Tracking)Current Consumption - Power Saving Mode Backup Mode: 12μA (39.6mW) (Backup Mode)GPS: L1 C/A, L1C*, L5, L2CGLONASS: L1, L2Galileo: E1, E5a, E5b, E6BDS: B1I, B1C, B2a, B2b, B2I, B3IQZSS: L1 C/A, L1C*, L5, L2CNavIC: L5SBAS: L1 C/APPP: B2bQZSS: L6Galileo HAS: E6Tracking Channels: 1040Horizontal Position Accuracy - Autonomous: 0.7mHorizontal Position Accuracy - RTK: 0.8cm + 1ppmVertical Accuracy - Autonomous: 2.5mVertical Accuracy - RTK: 1.5cm + 1ppmVelocity Accuracy Without Aid: 0.03m/sAccuracy of 1PPS Signal: 5ns (RMS)RTK Convergence Time: 5sCold Start: 28sWarm Start: 28sHot Start: 1.7sSensitivity - Acquisition: -146dBmSensitivity - Tracking: -160dBmSensitivity - Reacquisition: -155dBmMaximum Altitude: 10000mMaximum Velocity: 490m/sMaximum Acceleration: 4gUpdate Rate - Default: 10HzUpdate Rate - Max: 20HzAntenna Interface: External active antennaAntenna Power Supply: External or InternalUART: UART (x3)Baud Rate: 9600–3000000bpsDefault: 460800bpsProtocol: NMEA 0183/RTCM 3.xSPI: SPI* (x1)I2C: I2C* (x1)Operating temperature: -40°C to +85°CDevelopment note: *: Feature is still under developmentDocumentation includes design files, a hookup guide, CH342 USB driver information, QGNSS Software (v2.0), component documentation and a hardware repository.","vendor":"SparkFun","product_type":"GNSS RTK Breakout","in_stock":false,"options":[],"variants":[{"id":15854,"title":"Default Title","sku":"SF-GPS-26620","mpn":"GPS-26620","price":350.25,"on_sale":false,"in_stock":false,"available_quantity":0}]}
