Description:
1. Onboard mature and stable ESP-12F WIFI module, large capacity 4M BYTE FLASH;
2. The I/O port of the WIFI module and the UART program download port are all led out to facilitate secondary development;
3. Onboard AC-DC switching power supply module, power supply mode supports AC90-250V/DC7-30V/5v;
4. Onboard WIFI module RST reset button;
5. ESP-12F supports the use of development tools such as ECLIPSE/ARDUINO IDE, and provides reference programs under the development environment of ARDUINO;
6. Onboard 4 5V relays, output switch signal, suitable for controlling the working voltage of AC
Load within 250V/Dc30V;
7. On-board power indicator, 1 programmable LED and relay indicator.

Interface Description:

Burning port:
ESP8266's GND, RX, TX, and 5V are respectively connected to the GND, TX, RX, and 5V of the external TTL serial port module. IO0 must be connected to GND when downloading. After the download is complete, disconnect the connection between IO0 and GND;
Relay output:
NC: Normally closed, the relay is short-connected with COM before it is closed, and it is suspended after being closed;
COM: public end;
NO: Normally open end, the relay is suspended before being closed, and shorted to COM after being closed.

GPIO lead port introduction:

ARDUINO development environment building ESP8266 supports development tools such as ECLIPSE/ARDUINOIDE. It is relatively simple to use ARDUINO. The following is how to build ARDUINO development environment:
1. Install ARDUINO IDE 1.8.9 or the latest version;
2. Open ARDUINO IDE, click on the menu bar File-Preferences, after entering the preferences, click Add URL in "Additional Development Board Manager URL":
http://arduino.esp8266.com/stable/package_esp8266com_index.json,

3. Click Tools-Development Board-Development Board Manager in the menu bar, and then search for "ESP8266" to install the ARDUINO support package 2.5.2 or the latest version of ESP8266

Note: Since the download URL is from a foreign country, the access speed is relatively slow, and download errors may occur. Just wait a few more times when the network is good.

Program download:
1. Use a jumper cap/DuPont cable to connect the IO0 and GND pins, prepare a TTL serial port module (such as: FT232) to plug into the computer USB, the serial port module and the development board are connected as follows:

2. Click Tools in the menu bar-Development Board, select the development board as ESPINO (ESP-12 MODULE)
3. Open the program to be downloaded, click on the tool in the menu bar-Port to select the correct port number
4. After clicking "Upload", the program will be automatically compiled and downloaded to the development board, as follows:

5. Finally, disconnect the IO0 and GND connection, power on the development board again or press the reset button to run the program.
