L76K GPS HAT for Raspberry Pi
Supports Multi-GNSS systems: GPS, BeiDou (BDS), GLONASS and Q
FEATURES
The L76K GPS HAT 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.
- Standard Raspberry Pi 40PIN GPIO header, supports Raspberry Pi / Jetson / RDK series boards
- 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
- Supports AGNSS
- UART communication baud rate: 4800~115200bps (9600bps by default)
- Onboard battery holder, supports ML1220 rechargeable cell, for preserving ephemeris information and hot starts
- 4x LEDs for indicating the module operating status
- Comes with online development resources and manual (examples for Raspberry / Jetson / Arduino / STM32)
