Circuit Documentation
Summary
This circuit integrates various components to interface with an Arduino Nano microcontroller. The design includes a Neo 6M GPS Module for location tracking, a LORA_RA02 module for long-range communication, and a simple LED indicator with a resistor. Power management is handled by a 18650 Li-ion Battery connected to a lipo battery charger module, which in turn connects to a Step Up Boost Power Converter to regulate the voltage supplied to the Arduino Nano. A green button is included for user input. The circuit's functionality is controlled by embedded code running on the Arduino Nano.
