Raspberry Pi Pico GNSS expansion board L76K GPS Beidou (BDS) GLONASS QZSS A-GNSS For RP2040/RP2350
$13.9
Raspberry Pi Pico GNSS expansion board Based on L76K module Supports GPS, BeiDou (BDS), GLONASS and QZSS multiple satellite systems Supports A-GNSS function
Raspberry Pi Pico GNSS Expansion Board
L76K-based GNSS module
Product Features
This product is a Raspberry Pi Pico GNSS (Global Navigation Satellite System) expansion board based on the L76K module. It supports multiple satellite systems including GPS, BeiDou (BDS), GLONASS and QZSS. It can perform multi-system joint positioning and single-system independent positioning, and supports A-GNSS function. It has the advantages of fast, accurate positioning and low power consumption. When used with Raspberry Pi Pico / Pico 2, global positioning can be easily achieved.
- Onboard Raspberry Pi Pico interface, suitable for Raspberry Pi Pico series motherboards
- Supports GPS, BeiDou (BDS), GLONASS and QZSS multiple satellite systems
- Built-in low noise amplifier (LNA) to improve reception 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
- Provides complete supporting manuals (Raspberry Pi Pico's C/C++ and MicroPython example programs)
