I only needed 1, but for the price it is nice to have some extras around. I am using it in addition to a ESP32 in order to control my overhead door. Works great and have yet to have it fail on me. Works when it should, nothing else I can ask of it.

It's well thought out. It's easy to control the relay from a low power processor pin - just a couple mA will do the job. You can select whether the relay is triggered by a Vcc or ground signal, and the relay itself is SPDT. It works fine at 5v.The board has a power LED, which is annoying because power drain is an issue with battery circuits, and a separate LED which lights when the relay is energized, which is more acceptable. They can be removed.The relay itself is small and won't switch high currents at high voltages, but you can easily use it to control small lights, little motors or a larger relay.Pleased.

The input isolation is confidence-inspiring. The reversible activation logic is a great feature, although it means you need 5V power to the relay at all times. Worked flawlessly with Raspberry Pi GPIO.The documentation could definitely be better though... the Amazon product page gi es yiu all the connection diagrams, although I would have preferred some printed sheet with the relay itself.
