Overview The RPi Relay Board is a reliable relay expansion module for Raspberry Pi, designed to give your Pi the ability to control high-voltage or high-current electrical devices directly from its GPIO pins. Whether you're automating lights, controlling fans, or switching industrial equipment, this board makes it easy to integrate smart switching into your Rasp-berry Pi projects. This 5V relay module supports load switching of up to 5A at 250V AC or 5A at 30V DC, making it suitable for a wide range of home automation and industrial control applications. The module connects via a standard 40PIN GPIO header, making it compatible for Raspberry Pi 5/4B/3B+/3A+/2B/B+/Zero/Zero 2 W and more. To ensure safe operation, the board features photo-coupled isolation using an onboard optocoupler, effectively separating the Pi’s logic from the high-voltage switching side. This helps prevent signal interference and reduces the risk of damage to your development board due to power surges. Additional features include: ✅ Onboard LED indicators for relay switching status ✅ Jumper settings to redefine relay control pins ✅ Sturdy terminal block for easy connection of external loads ✅ Low-power 5V operation, directly powered by the Pi ✅ Open-source sample code in Python, shell, wiringPi, bcm2835, and WebioPi Whether you’re building a smart home system, a remote-controlled appliance, or a custom automation rig, the RPi Relay Board offers a simple and safe way to control AC or DC loads using your Rasp-berry Pi.
