Product description: Dual-band L1 + L5 GPS module with LC29H(AA) GNSS system - overlay for Raspberry Pi - Waveshare 25278
The LC29H GPS module with GNSS receiver for Raspberry Pi is a modern solution for applications requiring precise positioning, using dual-band L1 and L5 signals and compatibility with many GNSS systems. By reducing multipath effects in difficult urban environments, this module significantly improves positioning accuracy while maintaining minimal energy consumption . Equipped with a built-in low noise amplifier ( LNA ) and acoustic wave filter ( SAW ), it achieves exceptional sensitivity and resistance to interference. It supports a 40-pin GPIO expansion connector and has 4 LED indicators informing about the module's operating status. It is perfect for real-time monitoring and sharing economy applications, supporting the development of projects such as drones, smart agricultural devices, shared two-wheelers and many others.
The manufacturer has also prepared a user's guide with sample programs for Raspberry Pi .

EASY™ technology
EASY™ technology is an innovative solution used in the LC29H module. Its main goal is to improve the time to first location (TTFF) and positioning stability, even in conditions of limited satellite visibility. By using stored data, it allows for quick and effective positioning , also in situations where there is no satellite signal. Thanks to this application, positioning becomes much faster, which is crucial in applications where operating time and precision are important.
