When I connect my Arduino Uno board it instantly detects the board and shows it in the list. But when I connect my new Uno + Wifi board it doesn't detect it. I also manually selected Arduino Uno Wifi but it still gives me the message

Error uploading check if the selected board is currently available

How can I fix this?

This is the one that's not working:

Arduino Uno + Wifi

While this one I got does work:

Arduino Uno

  • Is it a genuine Uno?

  • I editted my question to contain the exact products. The power source inputs are different I don't know if that could have anything to do with it? Nov 20 '17 at 22:00
  • Install the USB drivers (CH340G). It's a cheap Chinese clone.

What you have there is a cheap Chinese clone. It uses the cheap CH340G USB chip instead of the proper ATMega16u2 that real Arduinos use.

Install the right drivers and it should start working.

  • Thank you this worked! But I just wonder, what's the downside of using the cheap clone? Nov 20 '17 at 22:05
  • They have a habit of dying easily. But they're cheap to replace.
