12V at barrel jack

I read many threads and in the documentation states the voltage provided to the Galileo should be 5V. However, when I place a voltmeter on the barrel jack that was provided in the kit, i see 12V. So I could cut the barrel jack end and wire that to my 12V battery, correct? I dont have a problem getting to 5V, I have plenty batteries and buck converters available, I just want to double check that this input is indeed 5V.

At which location on the board is 5V required? I do not see any other terminals for power besides the barrel jack. If someone could check their barrel jack for voltage i'd appreciate it.

Thanks

I see that this guy

had problems when trying to provide 5V at the barrel jack. He then switched to the Vin. This tells me that the 12V at barrel jack is being dropped on the chip at some point.

ok after reading this manual http://wearcam.org/ece516/ArduinoLinux_by_ManoelCarlosRamon_9781430268390.pdf http://wearcam.org/ece516/ArduinoLinux_by_ManoelCarlosRamon_9781430268390.pdf

on page 42 lists some of the highlights between gen1 and gen2.

Gen2:

The power regulator now supports voltage between 7-15V DC.

So, there you have it. Gen1 strictly requires that 5v barrel jack input, whereas the Gen2 handles 7-15V.
