Onboard mature and stable ESP-12F WIFI module, with a large capacity of 4M BYTE FLASH;<br /><br />2. All I/O ports and UART program download ports of the WIFI module are connected for easy secondary development;<br /><br />3. Onboard AC-DC switching power module, supporting AC90-250V/DC7-30V/5V power supply mode;<br /><br />4. On board WIFI module RST reset button;<br /><br />5. ESP-12F supports the use of development tools such as ECLIPSE/ARDUINO IDE and provides ARDUINO opening<br /><br />Develop reference programs in the environment;<br /><br />6. Onboard 4-channel 5V relays, outputting switch signals, suitable for controlling loads with operating voltages up to AC250V/Dc30V;<br /><br />7. Onboard power indicator light, 1 programmable LED and relay indicator light.<br /><br /><br />Interface Description<br /><br /><br />Burning mouth:<br /><br />The GND, RX, TX, and 5V of ESP8266 are respectively connected to the GND, TX, and RX of the external TTL serial module,<br /><br />5V, when downloading, IO0 needs to be connected to GND, and then disconnect the connection between IO0 and GND after the download is complete;<br /><br />Relay output terminal:<br /><br />NC: normally closed end, short circuited to COM before relay closing, suspended after closing;<br /><br />COM: Public end;<br /><br />NO: Constant start, the relay is suspended before closing and short circuited to COM after closing.<br /><br />Introduction to GPIO Export Ports<br /><br /><br />ARDUINO development environment setup<br /><br />ESP8266 supports development tools such as ECLIPSE/ARDUINOIDE, but using ARDUINO requires relative support<br /><br />Simple, here is the method for setting up the ARDUINO development environment:<br /><br />1. Install ARDUINO IDE 1.8.9 or the latest version;<br /><br />2. Open ARDUINO IDE, click on "File" in the menu bar - "Preferences", enter "Preferences", and then go to the "Additional Development Board Manager" website<br /><br />Click on 'Add URL' in the 'Address' section:<br /><br />http://arduino.esp8266.com/stable/package_esp8266com_index.json ,<br /><br /><br />3. Click on "Tools" -&gt;"Development Board" -&gt;"Development Board Manager" in the menu bar, and then search for "ESP8266" to install ARDUINO<br /><br />ESP8266 support package 2.5.2 or the latest version<br /><br /><br />Note: Due to the download URL being from overseas, the access speed is relatively slow, and there may be download errors. Please wait for the network to improve<br /><br />Just try a few more times in this situation.<br /><br />Program Download<br /><br />1. Use jumper caps/DuPont wires to connect the IO0 and GND pins, and prepare a TTL serial port module (such as FT232) to plug into the computer<br /><br />The connection methods for USB, serial module, and development board are as follows:<br /><br />2. Click on the tools in the menu bar - Development Board, and select ESPINO (ESP-12 MODULE) as the development board<br /><br />3. Open the program you want to download, click on "Tools" in the menu bar, select "Port" and choose the correct port number<br /><br />4. After clicking "Upload", the program will automatically compile and download to the development board, as follows:<br /><br />5. Finally, disconnect the connection between IO0 and GND, and the development board can be powered on again or press the reset button to run the program.<br /><br /><br />Product List:<br /><br />1X relay module<br /></p></div></div>
