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.
