ESP8266 Serial Wi-Fi Transceiver Module Send Receive LWIP AP+STA
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution£¬ allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry£¬ and the entire solution£¬ including front-end module£¬ is designed to occupy minimal PCB area.

ESP8266 Serial WIFI Module Communite Forum>> Detail about ESP8266: www.esp8266.com 1. High quality & low price 2. LWIP agreement 3. Support 3 modes: AP£¬ STA£¬ AP+STA 4. Perfect and simple AT commands Now your Arduino can get on WiFI without braking the bank. Use this module for your next Interet of Things project£¬ home automation£¬ Or remote sensor project. This module adats the ESP8226 IC for use over a serial connection using simple AT commands. No SPI interface or Know-How is required. Warnings: This module requires a 3.3 volt supply for VCC£¬ and 3.3V logic. It is not 5V tolant. Connect RX or TX on 5V Arduino will destroy this module. You must use a logic level converter£¬ or a 3.3V Arduino The 3.3V supply on the Arduino Uno has inadequate current capabilit to power this module. You must provide a separate£¬ higher 3.3V supply(about 300mA or better) The ESP8225 module is very new on the market and support and documentation for it is currently very limited.
