Description of ESP8266 ESP-12F 4 Channel Wifi IoT Smart Switch

ESP8266 ESP-12F 4 Channel Wifi IoT Smart Switch


The ESP-12F WiFi 4-Channel Relay Module is a highly integrated solution for smart home automation and IoT applications. Built on the reliable ESP8266 ESP-12F WiFi module, this relay board enables wireless control of up to four AC or DC loads via mobile apps or microcontroller-based systems. Designed with a robust AC-DC power module and secondary development in mind, it supports Arduino IDE, ECLIPSE, and other development platforms.

Key Features 


  • Built-in stable ESP-12F WiFi module with 4MB flash memory.
  • All GPIO and UART ports are broken out for easy secondary development.
  • Wide power input support: AC 90–250V / DC 7–30V / 5V.
  • Onboard reset button for the ESP module.
  • Compatible with Arduino IDE, ECLIPSE, and other development tools.
  • 4-channel 5V relays support up to AC250V or DC30V switching.
  • Onboard power LED, programmable LED, and relay status indicators.

Interface Description


Programming Port:

  • Connect GND, RX, TX, and 5V of ESP8266 to external TTL serial port (GND to GND, TX to RX, RX to TX, 5V to 5V)
  • Connect IO0 to GND during programming, then disconnect after upload

Relay Output:

  • NC (Normally Closed): Connected to COM before relay activation
  • COM (Common): Relay common terminal
  • NO (Normally Open): Connected to COM after relay activation

GPIO Pinout:

  • All standard GPIOs of ESP8266 are accessible via headers for custom functionality or sensor integration

Program Download Guide


  • Connect IO0 to GND using jumper wires or caps
  • Use a TTL-to-USB adapter (e.g., FT232) and connect to PC
  • Connect to the board: GND↔GND, TX↔RX, RX↔TX, 5V↔5V
  • Select the correct COM port and board type in Arduino IDE
  • Click "Upload"; the code will compile and transfer to the board
  • After upload, disconnect IO0 from GND and reset the board

Applications


  • Smart home device control
  • Wireless industrial automation
  • IoT-based switching systems
  • Remote ON/OFF control
  • Security and access automation
  • Smart farming systems
