Waveshare LC76G Multi-GNSS Module

The LC76G GPS Module is a Multi-GNSS (Global Navigation Satellite System) module, supports GPS, BeiDou (BDS), GLONASS, Galileo and QZSS systems, allows multi-system combined or single-system independent positioning. Supports EPO™ (Extended Predictive Orbit) and EASY™ (Embedded Assist System) function, provides a good positioning experience of fast, accurate, high-performance.

Features:

• Supports Multi-GNSS systems: GPS, BeiDou (BDS), GLONASS, Galileo, and QZSS
• Supports UART and I2C communication
• Built-in Low-Noise Amplifier (LNA) for improved reception sensitivity
