2 Channel Relay Module

The 2 Channel Relay Module is an easy-to-use interface board designed to control two high-voltage devices using low-voltage microcontrollers such as Arduino, Raspberry Pi, PIC, AVR, and 8051. Each relay works independently, allowing you to switch AC or DC loads safely and reliably.
It is widely used in home automation, industrial control, and DIY electronics projects.
