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
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
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.
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
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.
