Description

ESP8266 is a 3V WiFi module very popular for its Internet of Things applications. ESP 8266 maximum working Voltage is 3.6V and its very important to note. You must know how to power it, how to serial-connect it with Arduino safely, how to ping and many other things.

this serial Wifi  module add wireless ethernet connectivity to your microcontroller / Arduino through serial TTL pins (Rx and Tx). This means that your microcontroller / Arduino can talk to internet (send or recieve wirelessly).

Moreover, the module has onboiard microcontroller with its own firmware so it will do all the WiFi related tasks and thus free your main microcontroller / Arduino to do other tasks.

The module have many applications starting from sensors network to home automation.

ESP8266 has 8 pins, namely:

• RX

• VCC

• GPIO 0

• RESET

• CH_PD

• GPIO 2

• TX

• and GND
