Error: Arduino Nano on Device Library 404 Not Found


In the “Device Library” choosing Arduino Nano gives “404 Not Found” error


Is this on mBlock PC or web, and using what OS (Linux, Windows, etc.). Can you give a bit more info please? @ClaudioG


Windows 11, both mBlock PC and web,

Thanks for your time! @Best_codes


@ClaudioG I see, you mean the docs are missing. (The device image itself can be double-clicked on, and it will load it).

The docs page itself has been taken down or moved (see the old one here:, you will need to translate it).

Good luck!
