Product information

Description

ESP12-4R-MV is a compact Wi‑Fi relay module by No name that provides remote switching of electrical circuits. The board integrates multiple relays controlled via an ESP8266-based Wi‑Fi interface, enabling networked control of lighting, motors, pumps and other low- to moderate-power electrical loads. The module is designed for integration into DIY smart home projects, control panels and automation systems where compact size and wireless command are required.

Advantages

The relay board offers wireless control through a standard Wi‑Fi connection, allowing devices to be switched on or off remotely without additional wiring for control signals. Its compact footprint simplifies installation in enclosures or behind switch plates. Designed for maker and integrator use, the module is compatible with common ESP8266 tooling and firmware approaches, enabling flexible configuration for HTTP, MQTT or custom control schemes. The design includes multiple relays on a single PCB to reduce space and wiring complexity when controlling several circuits.

Suitable for

  • Home automation lighting control
  • Remote switching of small appliances and pumps
  • Integration into DIY smart home and IoT projects
  • Control panels and retrofit installations where wireless control is needed

Key specifications

  • Wi‑Fi connectivity based on ESP8266 platform for wireless control
  • Multiple SPDT or SPST relays mounted on a single compact PCB
  • Relay switching capability suitable for low- to moderate-current loads (refer to relay contact ratings before connecting high-power devices)
  • Operating voltage supply compatible with typical relay coil requirements (check module documentation for exact voltage and current consumption)
  • Compact physical dimensions allowing installation in confined spaces and enclosures
  • Control interfaces compatible with common network protocols (e.g., HTTP, MQTT) depending on installed firmware

How to use

Install the module in a suitable enclosure and provide the specified power supply to the board. Connect the controlled circuits to the relay output terminals following safety rules and local electrical codes. Configure the Wi‑Fi parameters and control method using the supported firmware or configuration interface; typical setup options include configuring SSID, password and control endpoints for HTTP or MQTT services. After configuration, test each relay switching action using the network commands or integration platform you selected. Ensure power is disconnected while making wiring changes.

Usage recommendations

Verify relay contact ratings against the intended load and use appropriate fuses or circuit protection. For AC mains applications, follow local wiring regulations and consider mounting the module inside a certified enclosure. Use isolation measures when integrating with safety-critical equipment and avoid exceeding the relay’s current and voltage limits.
