Nope, just 5V power.
See the photos; they show a power supply providing 5V and 160 mA, with dashes on the meter.
I did notice that if I bring up the voltage very slowly, I can see 0.00 and then something like 1.86 at around 3 volts, then it goes to dashes. Stays at dashes with the voltage up to 12V and 1 amp (had to use a serious resistor for that!).
By the way, this was a painful process. First I have to set things up to get the photos, save them. Then this site will not allow files > 1.0 MB to upload, so I have to go into GIMP and save the files with lower resolution, then upload and tag them.
