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 popularSparkFun 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 theL1,L2,L5, andL6/E6frequency bands of the GPS, GLONASS, Galileo, BDS, QZSS, and NavIC GNSS constellations. In addition, the module supports SBAS augmentation systems (WASS, 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 projects, such as intelligent robots, UAVs, precision agriculture, mining, surveying, and autonomous navigation.
Note: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.
