Pocket-GPS | Simple project with GPS Neo-6m and ESP32

In today’s fast-paced world, GPS technology has become an essential part of our lives. From navigation to tracking, GPS has a wide range of applications. In this blog, we will discuss a new project called “Pocket-GPS”, which is a compact, portable device that can receive and display values such as Altitude, Latitude, Longitude, Speed, and the number of satellites.

🌟 About the Project

in this project, with the help of GPS Neo-6M, We receive and display the values of Altitude, Latitude, Longitude, and Speed. also using TFT LCD I created a beautiful user interface for it. The main components used in this project are the GPS Neo-6M module, the TFT LCD (st7735), and the ESP32 microcontroller. By combining these components, we can create a device that provides accurate GPS information in real-time.

🎯 Features

The Pocket-GPS device has several features that make it unique and useful. The first and most important feature is its ability to display the values of Altitude, Latitude, Longitude, and Speed. These values can be displayed in real-time on the TFT LCD screen, making it easy to read and understand.

Another important feature is the number of satellites. The device can display the number of satellites it is currently connected to, allowing the user to know the quality of the GPS signal. This is important because the accuracy of the GPS values is directly related to the number of satellites connected.

Display the Values of:

• • Altitude
• • Latitude, Longitude
• • Speed
• • Number of Satellite

🧰 Components

The Pocket-GPS device uses three main components, each of which plays a critical role in the device’s functionality.

• • GPS Neo-6M
• • TFT Lcd st7735
• • ESP32

1. GPS Neo-6M: The GPS Neo-6M is a high-performance GPS module that provides accurate GPS information. This module is capable of receiving data from multiple satellites and can calculate the user’s position in real time.

2. TFT LCD (st7735): The TFT LCD (st7735) is used to display the GPS information. The TFT LCD screen has a resolution of 128×160 pixels, making it easy to read and understand. The screen also has a beautiful user interface that makes it easy to navigate through the device’s different functions.

3. ESP32 Microcontroller: The ESP32 microcontroller is the brain of the Pocket-GPS device. It controls all of the device’s functions and communicates with both the GPS Neo-6M and the TFT LCD. The ESP32 also has built-in Wi-Fi, which allows the device to connect to the internet and receive additional data, such as weather information.

🔌 Schematic

The Pocket-GPS device is easy to assemble. The connections between the GPS Neo-6M, the TFT LCD, and the ESP32 microcontroller are straightforward and can be made according to the table and schematic below.
