Remotely controlling any devices with your mobile phone or your laptop are all made easy with ESP8266 module develop by Espressif Systems.

The ESP8266 offers a complete and self contained Wi-Fi network solution, allowing it to either host the application or to offload all Wifi networking functions from another application processor.

When ESP8266 host application boot up directly from the external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements.

Alternately, serving as a Wifi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface.

ESP8266 on-board storage and processing capabilities allow it to be integrated with the sensors and other devices or other application specific devices through GPIOs with minimal development up-front and minimal loading runtime. With its high degree on-chip integration, which includes the antenna switch and power management converters, it is requires minimal external circuitry, and the entire solution, including front-end module is designed to occupy minimal PCB area.

ESP8266 has also sophisticated system-level features include fast sleep and awake context switching for energy efficient VoIP adaptable, radio biasing for low-power operation, advance signal processing, and spur cancellation and radio co-existence features for common cellular, Bluetooth, DDR, LVDR, LCD interference mitigation.
