L76K GNSS Positioning Module
Supports GPS, Beidou(BDS), Glonass, QZSS
UART Communication, Provides Multi-Platform Resources And Tutorials For Secondary Development And Integration
Features:
The L76K GPS Module is a Multi-GNSS (Global Navigation Satellite System) module, supports GPS, BeiDou (BDS), GLONASS and QZSS systems, allows multi-system combined or single-system independent positioning. Supports AGNSS function, built-in low-noise amplifier and sound surface filter, provides a good positioning experience of fast, accurate, high-performance.
- Supports Multi-GNSS systems: GPS, BeiDou (BDS), GLONASS and QZSS
- Built-in Low-Noise Amplifier (LNA) for improved reception sensitivity
- Built-in SAW Filter for enhanced noise reduction performance
- Support AGNSS
- Support 1PPS
- UART communication baudrate: 4800~115200bps (9600bps by default)
- Onboard rechargeable Li battery MS621FE, for preserving ephemeris information and hot starts
- 2x LEDs for indicating the module working status
- Comes with online development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32)
