Hi,

We have a some queries in Arduino UNO Rev3 schematics.

Where is the IOREF pin in schematic.

Which type of voltage ranges we will use for this connectivity.

Kindly provide the possible solution ASAP.

Thank You.

Where is the IOREF pin in schematic.
I believe IOREF is simply connected to +5V

Which type of voltage ranges we will use for this connectivity.
?
An UNO works on 5 volt logic.

Hi,

Thank you for your information. I have a another query regard to this.

If there is any option for Arduino UNO works on 3.3V logic .

This might work:

You can buy 3.3v Arduino Pro Mini boards 8MHz

You can get Arduino 101

Stop asking - the answer to all your questions is read the instructions/documentation

Lets see you make some effort!
