1 Channel 5V Relay Module for Arduino, Raspberry Pi & Microcontrollers

The 1 Channel 5V Relay Module is a reliable and compact switching device that allows your microcontroller—such as Arduino, Raspberry Pi, or ESP32—to control high-voltage devices like lights, fans, or pumps. With support for up to 10A @ 250V AC or 30V DC, it’s perfect for DIY projects, home automation, and smart system integration.

This module is optically isolated for safety, protecting your microcontroller from voltage spikes and surges. The onboard LED indicator provides real-time status of the relay, while the screw terminals allow for secure and easy wiring. It supports both Normally Open (NO) and Normally Closed (NC) connections, giving you flexibility in design.

Whether you’re building a smart home setup or an automated control system, this relay module delivers consistent performance in a compact footprint.
