ESP8266 Module Interface with Arduino

 

ESP8266 is a Wifi Module which is small in size and very useful for IoT (Internet of Things) Projects usingArduino. Here we are describing the how to interface ESP8266 Module with Arduino. Here we are the interfacing circuit as Module with PCB and design created in Proteus right now.

Here is the pinout of ESP8266 Module:

PIN	Description
1	GND
2	GPIO1 / U0TXD / SPI_CS1 (Connect with RX of Arduino)
3	GPIO2
4	CH_PD / CH_EN (Connect with 3.3v to enable the Module for Communication)
5	GPIO0 / SPI_CS2 (Use jumper with GND to Program ESP8266 Module GPIOs)
6	RESET (Hard reset use push button here to reset the ESP8266 module)
7	GPIO3 / U0RXD (Connect with TX of Arduino)
8	Vcc (Connect with 3.3v of Arduino)
