SparkFun Quadband GNSS RTK Breakout - LG290P (Qwiic)

The SparkFun Quadband GNSS RTK Breakout - LG290P (Qwiic) offers a powerful upgrade with the Quectel LG290P GNSS module providing exceptional positioning accuracy. The board's dimensions pin layout and connectors are exactly the same as the popular SparkFun GPS-RTK-SMA Breakout - ZED-F9P (Qwiic) featuring the same compact design and convenient Qwiic connector. Connect with ease using a variety of interfaces including UART SPI and I2C.The LG290P module is a quad-band multi-constellation high-precision RTK GNSS receiver. The module is capable of simultaneously receiving signals from the L1 L2 L5 and L6/E6 Frequency bands of the GPS GLONASS Galileo BDS QZSS and NavIC GNSS constellations. In addition the module supports SBAS augmentation systems (WAAS EGNOS BDSBAS MSAS GAGAN and SDCM) PPP services* (BDS PPP-B2b QZSS CLAS MADOCA-PPP and Galileo HAS) RTCM and RTK corrections for precision navigation with a fast convergence time and reliable performance.The built-in NIC anti-jamming unit provides professional-grade interference signal detection and elimination algorithms effectively mitigating multiple narrow-band interference sources and significantly improving signal reception performance in complex electromagnetic environments. Additionally the embedded algorithms ensure reliable positioning in complex scenarios such as urban environments and deep tree cover.With its high-precision and low-power consumption performance advantages this board is ideal for high-precision navigation applications such as intelligent robots UAVs precision agriculture mining surveying and autonomous navigation.*: Feature is still under developmentNote: Currently only the UART interface is supported by the module. Three UART ports are broken out to the USB-C connector (via CH342 USB-serial converter) 4-pin locking JST connector and BlueSMiRF 6-pin header. Additionally the corrections for some of the PPP services may not be implemented yet.
