Documented Code

No code has been provided for the microcontroller. The ESP32 would typically be programmed to initialize the serial communication with the Ublox NEO-M8N GPS module, parse the GPS data, and perform any required processing or actions based on the GPS information. The code would be written in a suitable programming language, such as C or C++, and uploaded to the ESP32 using an IDE like Arduino or ESP-IDF.
