A 4-channel relay module for controlling high-power devices from microcontrollers like Arduino, Raspberry Pi, and other development boards. Each relay has both normally open (NO) a nd normally closed (NC) terminals, giving you flexibility in how you wire your circuits. Status LEDs on each channel provide visual feedback on relay state. Key Features 4 Independent Channels – Control four devices separately NO and NC Terminals – Both connection types available per relay Status LEDs – Visual indication of each relay's state 5V Logic – Direct connection to most microcontrollers Mechanical Relays – Suitable for AC and DC loads Specifications Channels – 4 Operating Voltage – 5V DC Relay Type – Mechanical Outputs per Channel – NO (Normally Open), NC (Normally Closed), COM (Common) Compatibility Arduino Raspberry Pi (with level shifting) AVR, PIC, ARM, MSP430 microcontrollers Ideal For Home automation Appliance control Lighting systems Motor switching Industrial control projects Warning: When switching mains voltage, ensure proper electrical safety precautions. High voltage work should only be performed by qualified individuals. Show more
