I have a new Uno and if I measure with a multimeter the +5 voltage it is about 4.23. The 3.3 is 3.3. I put a simple voltage divider circuit (2000ohm + 222 Ohm) circuit across +5V and ground and measured the same voltage drop across bith resistors in series. The input voltage is 4xAA batteries that…

Uno +5V is low is this expected?

Thanks

I'll try that tonight.
