Topic: Uno wifi REV2 working only via USB (Read 773 times) previous topic - next topic



I am sorry for the silly question here, I am a complete newbie here. I received my Arduino Uno WIFI Rev2 and I am able to download sketches to it but it would only work when it is connected via a USB cable. I do not find it as part of the network list at all. How do I get it to work without the USB cable?
P.S. I have installed the WIFININA library.


Hello Ssonbol,

Thank you for sharing your question with the Arduino community.

Find answer to your question below:

After you upload a sketch to the board, that sketch will keep running constantly as long as the board has power. When the board is connected via USB to the PC it receiving power through the cable.

If you want your board to be cordless you can power the board with a battery either through the power input jack or VIN Pin. Please check the voltage you apply to the board is within the recommended range: For UNO WIFI Rev2 recommended:   7 - 12V.

I hope this was useful!

Good luck with your projects!
