ESP8266 ESP 12E WiFi Module is based on the ESP8266EX micro controller from ESPRESSIF. It is must have for any WiFi based projects nowadays. Many of the WiFi based IoT, and automation devices are using this module. This module has inbuilt WiFi along with MCU, and so does not need any external micro controller, it can be used directly.

It contains SoC with integrated TCP / IP protocol stack, and using it can give access to WiFi Network to any micro controller. It can also host application or otherwise offload the task of WiFi Networking from any micro controller.

This ESP 12E WiFi module comes with AT Commands Firmware, thereby allowing us to get functionality just like Arduino WiFi shield. The inbuilt firmware can also be replaced by uploading your own firmware, according to your needs, modules� memory and processor. Apart from all this, this module is very cheap, and has huge and growing community worldwide. It removes the need of external MCU based on the task at hand. And it has 7 GPIOs.
