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

The 2 Channel 5V Relay Module is a compact and reliable solution for controlling high-voltage devices using low-power microcontrollers such as Arduino, Raspberry Pi, ESP8266, and more. Each relay can handle up to 250V AC or 30V DC at 10A, making it ideal for switching lights, fans, pumps, and other appliances.

Designed with opto-isolation for enhanced safety and LED indicators for easy debugging, this module is great for DIY electronics, home automation, and industrial applications. It is triggered by an active low signal and features both NO (Normally Open) and NC (Normally Closed) contacts for flexible control.

Its small size makes it perfect for projects with limited space while still offering full control over two independent circuits.
