I have an Arduino Pro mini (328, 5v 16Mhz) and using the FTDI 5v breakout board to connect it to my PC via USB.
I noticed that when I measure the VCC (input voltage) coming from the USB, I am getting a read out of 6 volts instead of 5 volts. The AVR functions fine with this input voltage, but I have some external sensors that I would like to use that operate on 5 volts.
I am wondering if this is a consistent problem, has anyone noticed this same issue?
