GPS-RTK Rover LC29H(DA) Dual-band L1+L2 for Raspberry Pi

This GPS/RTK dual-band module with LC29H(DA) GNSS chip for Raspberry Pi offers you high-precision GNSS technology with centimeter-accurate positioning. Thanks to dual-band technology that uses both L1 and L5 frequencies, you can significantly improve the accuracy of your position determinations. The module supports multiple GNSS systems simultaneously and remains energy-efficient. With integrated amplifiers and filters, it achieves high sensitivity and strong interference immunity. It is ideally suited for real-time tracking systems and applications in the sharing economy, such as drones and smart agricultural machinery. The simple integration into your Raspberry Pi system allows you to immediately benefit from this advanced technology 

Info: If you are using Raspberry Pi 5, please change the UART serial port ttyS0 to the corresponding ttyAMA0. More info on the Waveshare Wiki.
