Wide-Input WiFi Relay for Custom IoT Control Boxes
The Relay ESP8266 10A 220V Network WIFI Module Input DC 7V-30V is a WiFi relay board with an onboard ESP8266, so the relay module itself can act as the controller. That makes it a strong choice for custom smart switches, control boxes, and network-based automation jobs.
Its wide DC input range makes it easier to deploy in 12V and 24V systems, while the relay output is ready for common appliance loads within rating.
Why you'll like it
- ESP8266 onboard: The relay can be the WiFi controller
- Wide DC input range: Good for 12V and 24V systems
- 10A relay output: Useful for many household or hobby loads
- Firmware flexibility: Great for custom IoT work
- Compact PCB: Easy to mount inside boxes and panels
What you can build
Use it for smart switches, MQTT relay nodes, HTTP-controlled loads, Home Assistant experiments, car or battery-based control panels, and custom WiFi automation enclosures.
Starter bundles
Pair it with an Arduino-compatible board, ESP32, or Raspberry Pi, plus jumper wires, a suitable power supply, and a small load for bench testing.
Recommended add-ons
Useful add-ons include terminal block, breadboard, power modules, fuses, and enclosure, especially when you are working with higher voltages or inductive loads.
