ESP8266 WiFi Shield for Arduino UNO – Easy Wireless Projects

Connect Your Arduino to WiFi Easily

Unlock wireless connectivity for your Arduino projects with the ESP8266 ESP-12E WiFi Shield. Designed for Arduino UNO and Mega boards, this easy-to-use Arduino WiFi Shield lets you connect your creations to the internet, start wireless communication, and control your devices remotely. Ideal for hobbyists, makers, students, and anyone looking to add wireless capability to their Arduino.

Key Features of the ESP8266 WiFi Shield

• Standard Compatibility: Fully compatible with Arduino UNO and Mega pinouts for easy stacking and setup. (Not for Nano or Mini Arduino boards.)
• Stable WiFi Module: Built-in ESP8266-12E chip for reliable wireless performance, featuring a metal shield for better signal and reduced interference.
• Power Management: 3.3V power supply with the same advanced chip used on official Arduino WiFi expansion boards; ensures safe and accurate voltage for the ESP8266.
• UART Communication: Easy serial (UART) interface with on-board TTL level shifter to protect the WiFi module from high voltage.
• Multiple Status LEDs: Four onboard LEDs (PWR, DFU, AP, STA) make it simple to see the status of your WiFi shield at a glance.
• Flexible Modes: DIP switch lets you quickly switch between operating and firmware upgrade modes.
• Expandable Design: Stackable headers mean you can add other Arduino shields on top for expanded functionality.
