1 Channel Relay Module

The 1 Channel Relay Module is an easy-to-use switching module that allows low-voltage microcontrollers to control high-voltage or high-current devices safely. It acts as an electrically isolated switch, making it ideal for controlling AC or DC loads using platforms like Arduino, Raspberry Pi, ESP8266, ESP32, and other microcontrollers.

This module comes with an onboard relay, optocoupler isolation, indicator LED, and screw terminals for secure connections. It is widely used in home automation, industrial control, IoT projects, and DIY electronics.
