Summary of the Circuit

This circuit integrates a Raspberry Pi Pico microcontroller with an HC-05 Bluetooth module and a GPS NEO 6M module. The Raspberry Pi Pico serves as the central processing unit, handling data from the GPS module and communicating wirelessly via the HC-05 Bluetooth module. The HC-05 enables Bluetooth connectivity, allowing the system to interface with other Bluetooth-enabled devices. The GPS NEO 6M module provides location data to the Raspberry Pi Pico.
