Greetings, dear All!

I wonder if the following MBs got the same DC-DC onboard power module:

J1900DC-ITX

N3150DC-ITX

J3160DC-ITX

The 1st one is declared to have 9-19 V input, 2nd and 3rd 19 V only.

I have a strange feeling that all of them will work fine with 12-14 V Pb accu, but not for sure.

Please could some one clear this for me, but the other way then just pointing me to MB specifications/manuals?

I'm planning to build a linux box and powering it directly from UPS battery terminals in the future.

Thanks a lot in advance!
