The ESP8266 Serial WiFi Expansion Board Module, also known as the ESP-12E UART Wireless WiFi Shield TTL Converter, provides a simple way to connect Arduino boards to WiFi networks. Unlike traditional setups that require multiple components and wiring, this module can be directly attached to an Arduino. By configuring the DIP switch paths according to the shield’s operating mode, the Arduino can be easily programmed to access WiFi.
Additionally, the module can be used independently without an Arduino, since all ESP-12E pin-outs are available for direct access, making it versatile for both beginner and advanced projects.
