GPS-Tracker-using-STM32

A custom PCB design for an STM32-based GPS tracking system using the SIM808 GPS/GPRS module.

This project is based on the concept of a GPS tracker using an STM32 microcontroller and SIM808 module. The main focus of this project is the schematic design, component selection, PCB layout, routing, and design-rule verification using KiCad.

⚠️ Project Status: PCB design completed in KiCad.
The PCB has not been manufactured or physically tested yet.

📌 Project Overview

The objective of this project is to design a compact custom PCB capable of integrating the main hardware required for a GPS tracking system.

The PCB is designed around:

STM32 microcontroller
SIM808 GPS/GPRS module
DC-DC power regulation
GPS and GSM/GPRS antenna interfaces
SIM card interface
UART communication
Programming/debugging interface
Status indicators
Supporting capacitors, resistors, and protection components

The complete PCB was designed using KiCad EDA.

Questions

How big is the STM32 GPS Tracker PCB?

It measures 56 × 59.8 mm and has 4 copper layers, 1.6 mm thick.

What parts does the STM32 GPS Tracker use?

53 parts, built around the SIM808, TPS5430DDA, SMF05CT1G and AO3407A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the STM32 GPS Tracker KiCad files?

From the Manideep136/GPS-Tracker-using-STM32 repository on GitHub, at the commit this page was made from: the board is STM32 GPS Tracker/STM32 GPS Tracker.kicad_pcb and its schematic STM32 GPS Tracker/STM32 GPS Tracker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the STM32 GPS Tracker design in my own project?

Its repository states no licence, so its author keeps all rights: ask Manideep136 before reusing the design.
