Product description: GNSS/GPS/BDS/QZSS L76B overlay for Raspberry Pi Pico - Waveshare 20072
Waveshare's GNSS module that allows you to use multiple GPS satellite systems with your Raspberry Pi Pico module. The overlay for the RPi Pico is based on the L76B chip and supports satellite systems such as GPS, BDS and QZSS. It supports D-GPS, SBAS (WAAS/EGONS/MSAS/GAGAN). It communicates with the microcontroller via UART interface. A GPS antenna has also been included in the set.
The manufacturer has also prepared a user guide with sample programs for Raspberry Pi Pico.
A GPS antenna is also included in the kit.Main features of GPS module for Raspberry Pi Pico
