GPS_Tracker_Final

This document provides a formal blueprint for advancing the project with the following objectives:

• PCB Design: Integration of RAK11720 and NEO6 GPS modules on a PCB.

• Power Management: Inclusion of a Li-ion battery input and a charging circuit based on the MCP73831, along with a USB Type-C charging interface.

• Enclosure: Utilization of the Altinkaya DM-005 case for robust and aesthetic packaging.

• Battery Voltage Monitoring: Implementation of a voltage divider feeding the ADC, with an automated shutdown if the battery voltage falls below 3.68V.

• Additional Components: Incorporation of LS3DH, HT21SMD, and TPS7250 to enhance system functionality.

• System Architecture

  The tracking device is designed around several core elements:

  1. RAK11720 LoRa Module: Enables long-range wireless communication.

  2. NEO6 GPS Module: Provides precise geographic positioning data.

  3. MCP73831 Charging Circuit: Manages safe charging of the Li-ion battery.

  4. USB Type-C Port: Facilitates modern and user-friendly charging.

  5. Battery Voltage Monitoring: Utilizes a voltage divider connected to the ADC; the system initiates shutdown if voltage drops below 3.68V.

  6. Additional Components:

     • LS3DH Sensor: Integrated for motion detection and orientation sensing.

     • HT21SMD Module: Added for enhanced sensing capabilities.

     • TPS7250 Regulator: Ensures efficient voltage regulation and power management.
