Product Description (Detailed):

The ESP13 ESP8266 Wi-Fi Shield is a powerful and easy-to-use Wi-Fi expansion board designed for Arduino UNO, MEGA2560, and other boards using standard Arduino headers. Based on the popular ESP8266 module, this shield allows you to connect your Arduino projects to the internet, host web servers, or communicate via TCP/IP and HTTP.

With support for serial communication (UART) using AT commands, this shield makes it simple to build wireless IoT applications without needing to program the ESP8266 directly. Simply plug it into your Arduino board and start sending or receiving data over Wi-Fi.

How to Use:

Basic Setup (Arduino UNO + ESP13 Shield):

1. Stack the Shield onto your Arduino UNO or MEGA.

2. Select communication method:

   • Use jumper settings to route ESP8266 TX/RX to Arduino pins (usually D0/D1).

3. Open the Arduino Serial Monitor or use a library like WiFiEsp or SoftwareSerial to control the module via AT commands.

4. Use AT commands like:

   • AT+CWMODE=1 – set Wi-Fi mode

   • AT+CWJAP="SSID","password" – connect to Wi-Fi

   • AT+CIPSTART="TCP","your_server",80 – open TCP connection

 Alternatively, you can flash NodeMCU or custom firmware onto the ESP8266 for advanced use.

Applications:

• Arduino web server projects

• Remote control of sensors and relays

• Wireless data logging

• Home automation and IoT systems

• Smart switch and light control

• Wireless sensor monitoring

Package Includes:

• 1 × ESP13 ESP8266 Wi-Fi Shield Board
