Where is the AVR Boards?

Hi Everyone.

Ide 2.3.6
Win11.

I just notice that I have no AVR Boards to select.
Where are they?

Hi @mikedb. Arduino IDE 2.x automatically installs the "Arduino AVR Boards" platform, so its absence is a bit surprising.

Was there a time when you did see "Arduino AVR Boards" listed under Arduino IDE's Tools > Board menu, or has it always been this way? If the former, can you think of anything you did between the last time it was present that might be relevant?


You can install the "Arduino AVR Boards" platform via the Arduino IDE Boards Manager. I'll provide instructions you can follow to do that:

  1. Select Tools > Board > Boards Manager... from the Arduino IDE menus to open the "Boards Manager" view in the left side panel.
  2. Find the "Arduino AVR Boards" entry in the list of boards platforms.
  3. Click the "INSTALL" button at the bottom of the entry.
  4. Wait for the installation process to finish, as indicated by a notification at the bottom right corner of the Arduino IDE window:

    Successfully installed platform ...

You should now see the boards of the "Arduino AVR Boards" platform under the Tools > Board menu in Arduino IDE.

  1. I cannot remember that I ever saw or used the AVR Boards.
  2. So I cannot think of anything that I did the would cause the missing AVR Boards.

When I open the IDE 2.3.6 again I saw this message below and just clicked on YES.

Then I selected Arduino UNO and the AVR Boards is back.
Thanks.

Great news! Clicking that button accomplished the same thing as the procedure I described in my previous reply.
