ESP8266 wireless wi-fi module is a wireless module for serial Uart Arduino .

A miniature wireless wi-fi module based on the latest chip ESP8266 with integrated protocol stack TCP / IP and running AT-commands. There are two ways to use the chip:

  1. a bridge UART-WIFI, when the module is based on the ESP8266 is connected to the existing solutions on the basis of any other microcontroller and controlled by AT-commands, providing communication solutions to infrastructure Wi-Fi;
  2. implementing a new solution that uses the chip ESP8266 as the control of the microcontroller.

Pins of ESP8266 wireless wi-fi module :

  • Vcc - power + 3.3V (3.6V maximum)
  • GND - general
  • TXD - Data Transfer (3.3V levels)
  • RXD - receiving data (the level of 3.3V)
  • CH_PD - off module (low level of activity to include the module must be submitted Vcc)
  • GPIO0 - concluded general purpose 0
  • GPIO2 - concluded general purpose 2
  • RST - Reset module (low active)

ESP8266 wireless wi-fi module is widely used in the systems of "smart home" in mesh-networks, IP-cameras, wireless sensors, portable electronics, and so on.
