The LC76G is a multi-GNSS positioning module that supports GPS, BeiDou (BDS), GLONASS, Galileo, and QZSS satellite systems. It allows multi-system combined or single-system independent positioning for fast, accurate location data. The module communicates via UART or I2C, making it compatible with a wide range of microcontrollers and single-board computers.

With built-in EPO (Extended Predictive Orbit) and EASY (Embedded Assist System) functions, the module achieves faster time-to-first-fix. An on-board rechargeable lithium battery preserves ephemeris data for hot starts, and two status LEDs indicate module operation.
