==Functional Features==
1. Onboard mature and stable ESP-12F WiFi module, with a large capacity of 4M Byte Flash 
2. All I/O ports and UART program download ports of the WiFi module are connected for easy secondary development 
3. On board WiFi module RST reset button 
4. ESP-12F supports the use of development tools such as Eclipse/Arduino IDE and provides reference programs for Arduino development environment 
5. Onboard 2-channel 5V relays, outputting switch signals, suitable for controlling loads with operating voltages below AC 250V/DC30V 
6. Onboard power indicator light, 1 programmable LED and relay indicator light 

==Hardware Introduction and Explanation==
1. Board size: 78 * 47mm Weight: 38g

'''2, Interface Introduction''' 
[[Image:WF-6-2-04.jpg|600px|]] 
Burn in port: Connect GND, RX, TX, 5V of ESP8266 to the external TTL serial module's GND, TX, RX, 5V respectively. When downloading, connect IO0 to GND, and then disconnect the connection between IO0 and GND after downloading is complete 
Relay output terminal: 
NC: normally closed end, short circuited to COM before relay closing, suspended after closing 
COM: Public End 
NO: Normally, the relay is suspended before closing and short circuited to COM after closing

'''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. After clicking "Upload", the program will automatically compile and download to the development board, as follows:
