L76K GPS HAT
Raspberry Pi GNSS Expansion Board

Support GPS / BeiDou (BDS) / GLONASS / QZSS multi-satellite systems

Product Features

This product is a GNSS (Global Navigation Satellite System) module that supports multiple satellite systems including GPS, BeiDou (BDS), GLONASS and QZSS. It can perform multi-system joint positioning and single-system independent positioning, supports A-GNSS function, has built-in low-noise amplifier and surface acoustic wave filter, and is a Raspberry Pi GNSS expansion board that can provide users with fast, accurate and high-performance positioning experience.

• Based on the Raspberry Pi 40PIN GPIO interface design, suitable for Raspberry Pi, Jetson and RDK series motherboards
• Supports GPS, BeiDou (BDS), GLONASS and QZSS multiple satellite systems
• Built-in low noise amplifier (LNA) to improve receiving sensitivity
• Built-in SAW filter to enhance noise elimination performance
• Support A-GNSS function
• Support serial communication baud rate range: 4800bps ~ 115200bps (default 9600bps)
• Onboard battery holder, can be connected to ML1220 rechargeable battery, used for power failure to save ephemeris data and fast hot start
• Onboard 4 LED indicators for easy viewing of module operating status
• Provide complete supporting manuals (Raspberry / Jetson / Arduino / STM32 sample programs, etc.)
