This is a general GNSS module which supports Multi-GNSS systems: GPS, BDS, and QZSS, with advantages such as fast positioning, high accuracy, low power consumption, etc.

This module is great for use in microcontroller-based projects as well as with the popular SBCs on the market today and would be perfect in your next Raspberry Pi, Arduino, or Adafruit Feather HUZZAH project. 

Online development resources are available, which include wiring guidance and example code, with additional information being found on the Product Wiki & Manual.
