Ok. Thank you. And yes, the 5v usb cable is run from the pc. I have a phone charger available as well. It reads 4.74v at pc5v and pcgnd.
Does it matter?

phone chargers are not regulated very well
so you will be better off either using the PC's USB port or using a regulated 5V power supply to power the 5V side of the breakout board

I use exactly that BoB with a 12/5v dual power supply from a defunct external hard drive. It works fine !
