U-Blox M8 GPS (Serial)
File:TArduino UBlox M8 GPS Serial.png
Summary
This component interfaces with a U-Blox M8 GPS module using a serial (UART) connection. It processes raw satellite data to provide comprehensive navigation information.
Description
The **U-Blox M8 GPS (Serial)** component reads data from the GPS module via a serial port. It parses NMEA sentences or UBX messages to extract useful information including geographical location, precise time, speed, altitude, and detailed satellite data.
