What is a WiFi module ESP8266 ?
- A WiFi module ESP8266 is a microcontroller made by Espressif.
It is loaded with features. The most important being wi-fi protocol. The best part is that they are dirt cheap and more powerful than an Arduino. - The wifi module ESP8266 is an extremely cost-effective board with a huge, and ever-growing, community.
- The ESP8266 WiFi Module with SOC with integrated TCP/IP protocol stack, this protocol stack allows the microcontroller connects to Wi-Fi.
- The ESP8266 is capable of an act as a server i.e. hosting an application or client, a client will receive all Wi-Fi networking functions from another processor.
- ESP 8266 compatible with Arduino board, you can program ESP using ARDUINO IDE, popular as WiFi module for Arduino.
- Each ESP8266 module comes with pre-programmed an AT command set firmware.
- ESP 8266 available from esp-01 module to esp-12e module.
- More common module are esp-07 and esp-12e.
ESP 8266 can be used in following applications
