It offers a complete and self-contained Wi-Fi networking solution,Website: , 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.
