== Summary ==
The LC76G is a multi-GNSS module from Waveshare (SKU WSAL24370) that supports GPS, BDS, GLONASS, Galileo and QZSS. It outputs NMEA 0183 data over UART/I²C and provides PAIR commands to configure baud rate, update rate, satellite systems and start types.

== Technical overview ==
* Supported GNSS systems: GPS, BeiDou (BDS), GLONASS, Galileo and QZSS; multi-system combined or single-system operation is possible.
* Dimensions 9.7 × 10.1 × 2.4 mm, weight approx. 0.5 g (LCC package).
* Operating temperature range -40 °C to +85 °C; storage temperature range -40 °C to +90 °C.
* Interfaces: UART (TX/RX), I²C (SDA/SCL), PPS timing pulse, reset, VCC/GND; antenna connector for active and passive antennas with short/open detection.
* NMEA 0183 output includes e.g. $GPRMC, $GPGGA, $GPZDA, $GNGNS, $GPGSA, $GPGSV, $GPGLL, $GPGST; prefixes such as GP/BD/GL/GA/GN identify the respective system or multi-system mode.
* PAIR commands allow configuring serial baud rate ($PAIR864), position update rate ($PAIR050), NMEA output type/rate ($PAIR062) and enabled satellite systems ($PAIR066).
* Start commands: $PAIR004 = hot start, $PAIR005 = warm start, $PAIR006 = cold start, $PAIR007 = clear configuration and cold start.
* The wiki provides demos for Raspberry Pi, Arduino, Raspberry Pi Pico, ESP32 and Jetson Nano; on Windows, connection is via a USB-UART adapter using Minicom/U-center.
* Default module baud rate is 115200 bps; however, 9600 bps was used in the example for Minicom debugging.
* The GGA sentence contains altitude in meters plus geoid/ellipsoid height difference; RMC provides UTC time, position, speed, heading and date.

== Notes and version constraints ==
* The source page contains placeholders ({name3}, {userDefinedInfo}, etc.), indicating an incomplete template; these were removed.
* Some details (e.g., exact compatibility lists, prices, stock, certifications or warranty) are absent from the source and must not be invented.
* Version-sensitive steps (e.g., Pi 5 vs. older boards, ESP32 plugin versions) require human confirmation before implementation.
* In bad weather or heavy obstruction, the first fix may take longer or fail; this is not a fault of the module itself.
* All PAIR checksums must be recalculated after any change; the values listed in the wiki apply only to the examples shown.
* No statements about safety certifications or warranty are present in the source material; such claims were deliberately omitted.
