Product description
GNSS/GPS module for Raspberry Pi Pico. Pico-GPS L76K is a navigation and positioning system for development projects based on Raspberry Pi Pico or Pico 2. The module provides access to positioning services with support for multiple satellite systems, and is optimized for high-speed communication and low power consumption. Delivered including GNSS/GPS antenna. Waveshare maintains a wiki with manuals, schematics, and programming examples for C/C++ and MicroPython.
Features:
- Support for multiple GNSS systems: GPS, BeiDou (BDS), GLONASS and QZSS
- Built-in low-noise amplifier (LNA) and SAW filter for improved reception sensitivity and noise reduction
- Support for A-GNSS (assisted GNSS) for faster fix under optimal conditions
- UART communication, with baudrate 4800–115200 bps (9600 bps default)
- Update rate (GNSS data): 1 Hz standard, up to 5 Hz when required
- Backup battery: holder for ML1220 rechargeable battery, preserves ephemeris data and enables fast hot start
- Four LED indicators for operating status
- Direct physical connection to Raspberry Pi Pico via pin header
- Development resources with demonstration examples for C/C++ and MicroPython
