Summary
This component interfaces with a U-Blox M8 GPS module over the I2C communication protocol. It processes satellite data to provide location, time, speed, and other navigation information.
Description
The U-Blox M8 GPS (I2C) component allows for easy integration of a high-precision GPS module. It communicates using the I2C bus, minimizing the number of required pins. The component decodes messages from the GPS to output structured data like latitude, longitude, altitude, speed, course, and satellite information.
