ESP8266 Wifi Module tutorial introduction

ESP8266 Serial Wi-Fi Wireless Transceiver Module for IOT offers wide variety and range of complete self controlled and contained Wifi solutions for connected devices of all time. The beauty of this device is this device allow us to load the entire application on this device or its wifi services can be used by other device or application systems , When offering and hosting the application or used by external application in itself it is fully capable of booting itself directly from external memory. It has its own improved cache system to work at high speed.

Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface. Another best feature of this device when it serve as Wi Fi adapter then we can connect external microcontroller to connect its wifi services with the embedded applications in the external microcontrollers. This way this device may be used as a simple wifi adapter.
