A Relay Board, as we know, is used to turn fans, lights, or other devices on/off by isolating them with a microcontroller. It is not important that you are a beginner or a pro in the electronics, but if you are doing a DIY project using your favorite Raspberry Pi and/or Arduino device, then it is recommended that you use a Best Relay Board to provide the isolation between the microcontroller and the device you are controlling. Not all types of relay boards are compatible with the Raspberry and Arduino both. And purchasing a separate board for both the devices is a waste of money and resources. So, I have made this list of the “Relay Board for Raspberry Pi and Arduino”, which will give you a filtered option to choose a perfect Raspberry Pi relay shield and an Arduino relay shield.
