These devices are sold as being "for Arduino" but they are NOT directly compatible with Arduino or other ESP32/ESP8266 devices. These are COMPONENTS that can be assembled, along with another circuit board and a handful of other components, which will THEN be compatible with Arduino.So, if you are an electrician or electrical engineer and know the other components you will need, this might be for you. The device *appears* to be great, for its intended purpose. It's just that the "purpose" is not to connect to an Arduino.One dead give-away of this is that there are no markings on the pins and no wiring diagram included. You BETTER know what all 5 pins do and how to connect them to the OTHER SEVEN components you will need to make this work. Or better yet, if you want to make a hobby/Arduino project, JUST BUY the "Relay module/Relay Switch" which *IS* clearly labeled and DOES work immediately out-of-the box with Arduino.

Was packaged nicely and worked out well. Used to repair my sofa’s auto footrests circuit.
