The 2 Channel 5V Relay Module is a compact and reliable switching solution for projects that require control of two high-voltage devices. Whether you’re building a smart home automation system, remote appliance control, or a robotic project, this relay board allows your microcontroller to safely control AC appliances (up to 250V) or DC loads (up to 30V).
It features opto-isolation to protect your board from voltage spikes and surges and includes LED indicators to show the working status of each relay. With support for logic-level triggers (3.3V to 5V), it’s fully compatible with Arduino, ESP8266, ESP32, Raspberry Pi, and other development boards.
This dual relay module is widely used in home automation, smart farming, IoT projects, DIY electronics, and industrial control systems.
