    Hi, I bought a opto-isolator relay from ebay. But I have no idea how to connect to my Arduino (Pro Micro that don't have the function to produce 5V and 3.3 V power from it). I provide the diagram of the relay.

    Regards,
    John

    Where is the datasheet? Unless someone happens to recognize the relay from that tiny picture, that picture is worthless. And it is not a "diagram" it is a photo of the relay.

    I bought it from ebay. They don't provide diagram. There is three pin on the left side (JVCC, VCC, GND). There are four pin on the right side (VCC, CN1,CN2, GND).
