'''4, Arduino development environment setup''' 
ESP8266 supports development tools such as Eclipse/Arduino IDE, and using Arduino is relatively simple. Here is the method to build an Arduino development environment: 
1. Install Arduino IDE 1.8.9 or the latest version 
2. Open the Arduino IDE, click on "File" ->"Preferences" in the menu bar, enter "Preferences", and then click on "Add URL" in the "Additional Development Board Manager URL": http://arduino.esp8266.com/stable/package_esp8266com_index.json , 
[[Image:WF-6-2-05.png|600px|]] 
3. Click on "Tools" ->"Development Board" ->"Development Board Manager" in the menu bar, and then search for "ESP8266" to install Arduino support package 2.5.2 or the latest version for ESP8266 
[[Image:WF-6-2-06.png|600px|]] 
Note: Due to the download URL being from overseas, the access speed is relatively slow and there may be download errors. Please try a few more times when the network is good 
'''5, Program Download''' 
1. Use a jumper cap to connect the IO0 and GND pins, and prepare a TTL serial port module (such as FT232) to plug into the computer USB. The connection method between the serial port module and the development board is as follows: 
{| class="wikitable" style="width:800px"
|-
|TTL serial port module || ESP8266 development board
|-
| GND ||GDN
|-
|TX||RX
|-
|RX||TX
|-
|5V||5V
|} 
2. Click on the tool in the menu bar - Development Board, select ESPino (ESP-12 module) as the development board 
3. Open the program you want to download, click on "Tools" in the menu bar, select "Port" and choose the correct port number

'''4, Arduino development environment setup''' 
ESP8266 supports development tools such as Eclipse/Arduino IDE, and using Arduino is relatively simple. Here is the method to build an Arduino development environment: 
1. Install Arduino IDE 1.8.9 or the latest version 
2. Open the Arduino IDE, click on "File" ->"Preferences" in the menu bar, enter "Preferences", and then click on "Add URL" in the "Additional Development Board Manager URL": http://arduino.esp8266.com/stable/package_esp8266com_index.json , 
[[Image:WF-6-2-05.png|600px|]] 
3. Click on "Tools" ->"Development Board" ->"Development Board Manager" in the menu bar, and then search for "ESP8266" to install Arduino support package 2.5.2 or the latest version for ESP8266 
[[Image:WF-6-2-06.png|600px|]] 
Note: Due to the download URL being from overseas, the access speed is relatively slow and there may be download errors. Please try a few more times when the network is good 
'''5, Program Download''' 
1. Use a jumper cap to connect the IO0 and GND pins, and prepare a TTL serial port module (such as FT232) to plug into the computer USB. The connection method between the serial port module and the development board is as follows: 
{| class="wikitable" style="width:800px"
