L76K Multi-GNSS Module
TheĀ L76K GPS ModuleĀ is a Multi-GNSS (Global Navigation Satellite System) module. It can acquire and track any mix of 3 multiple satellite constellations, providing simultaneous GPS, GLONASS, BeiDou, Galileo and QZSS open service L1 reception capability. This increases the number of visible satellites and reduces time-to-first-fix, allowing accurate navigation in settings such as urban canyons.Ā
The module also has AGNSS (Assisted GNSS) to significantly improve the start-up performance by providing the necessary data to the device via a radio network instead of the slow satellite link, essentially "warming up" the receiver for a fix, a low-noise amplifier for improved reception sensitivity, a SAW filter for enhanced noise reduction performance, and online resources and a manual for ease of use.Ā
It's also compatible with multiple platforms including Raspberry Pi, Pico, Arduino, ESP32 and STM32.
Note: The Raspberry Pi is NOT included
Features
- Supports Multi-GNSS systems: GPS, BeiDou (BDS), GLONASS and QZSS
- Low-Noise Amplifier (LNA) for improved reception sensitivity
- SAW Filter for enhanced noise reduction performance
- AGNSS
- 1PPS
- UART communication baud rate: 4800~115200bps (9600bps by default)
- Rechargeable Li battery MS621FE, for preserving ephemeris information and hot starts
- 2x LEDs for indicating the module working status
- Online development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32)
