Debug ESP8266 with a modified UNO

Introduction
Today we will use UNO R3 as a serial converter and debug ESP8266 with a modified UNO.
Components
– 1 * Adeept UNO R3 Board
– 1 * ESP8266 Module
– 1 * Breadboard
– 1 * USB Cable
– 1 * Male To Male Jumper Wires
– 6 * Male To Female Jumper Wires

Experimental Principle 
The ESP8266 needs a serial port for communication.To communicate with the ESP8266, you have to use a serial port converter.If you do not have serial converter, use a UNO board without the Mega328 chip. Be careful not to break the chip’s pins when removing the Mega328 chip.
Remove as shown below:
