I can't upload sketch to Arduino WiFi Rev.2 Dev Board

Development Tools IDE 1.x
2

Hi @kstc05. Despite the similar names, the Arduino Uno WiFi Rev2 board you have and the "Arduino Uno WiFi" board you have selected from the Arduino IDE's Tools > Board menu are completely different boards. You can't upload to the Uno WiFi Rev2 with the Uno WiFi board selection. This is the cause of the error.

In order to use it, you'll need to install the "Arduino megaAVR Boards" platform of the Arduino Uno WiFi Rev2. Please do this:

  1. Select Tools > Board > Boards Manager from the Arduino IDE's menus.
  2. Wait for the update to finish.
  3. Scroll down through the list of available boards platforms until you see "Arduino megaAVR Boards". Click on it.
  4. Click the Install button.
  5. Wait for the installation to finish.
  6. Click the Close button.
  7. Select Tools > Board > Arduino megaAVR Boards > Arduino Uno WiFi Rev2 from the Arduino IDE's menus.

Now try uploading again.
