ESP8266 Relay Module for DIY Smart Switches

This intelligent relay module is built around an ESP-01S Wi-Fi module and is intended for makers who want to create their own remote-controlled switches. It arrives ready to use with APP and LUA source code provided so developers can integrate mobile-app control without starting from scratch.

PCB Construction with 10 A Relay Contacts

The board uses a DC 5 V supply and carries a relay rated for 10 A at 250 VAC, 125 VAC, 30 VDC and 28 VDC, making it suitable for switching mains-powered loads. The compact PCB measures 37 by 25 mm and weighs 16 g, allowing it to fit inside standard electrical boxes or project enclosures.

Upgrade from Standalone Relay Boards

Builders moving up from basic relay modules that lack network connectivity gain wireless control and programmable logic in a single package. The jump is worth it when a project requires remote scheduling or sensor-driven automation without adding a separate microcontroller.
