8-Channel WIFI Relay Module with 5V and 7-28V power supply options.

Using Blynk or other Apps, this module can easily be remotely controlled to switch 8 different loads of up to 10A AC/DC.


  • Onboard ESP-12F WIFI module with 4MB Flash Memory
  • Onboard AC-DC switching power supply module
  • ESP-12F supports development tools such as Arduino IDE
  • Onboard 5V relays controlling AC or DC loads up to 10A
  • On-board power indicator and indicator for every relay


  • The GND, RX, TX, and 5V of ESP8266 are accessible on the mainboard. There you can connect a serial TTL connection or, for example, a USB UART converter like FT232 or CH340
  • 5V, IO0 needs to be connected to GND for downloading your program and needs to be open for normal operation
  • It is easy to see which IO port pin is connected to which relay. The ADC input of the ESP8266 module is also available for reading analog values between 0 and 1023. Since it is a direct connection to the pin, the input voltage range on that pin is limited to 0-1V.
