How to power up intel galileo with a battery

Use a low cost DC-DC converter, this would be the most efficient and therefore give you best battery consumption

like one of these  NMXS1205UC MURATA POWER SOLUTIONS DC / DC Converters - Isolated Board Mount Single Output | 70K3967 | Newark element14 C…

this is a quality one from Newark, you can also get ones from Ebay for a few $$ if your willing to wait http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR3.TRC2.A0.H0.Xbuck+convertor&_nkw=buck+convertor&_sacat=0

I am assuming you need at least 1A at 5V

Hope this helps

So can i use a linear regulated supply ...like 7805 with output current max 1.5A at 5V...? ...for powering the galileo...?

element14jamie  ... Jamie, another thing to look at

Sorry you did not get a reply earlier, I responded directly from the email as it says I can but it is not showing up here, did you get a response ?

anyway, Yes you could use a 7805 regulator but it would be very inefficient, much less than 50% as you would be dropping all 7V across it and at one amp thats 7W, add this to the 5W (Assuming 1A again) thats 12 W consumed for only 5W used

A Buck converter will be in excess of 90% efficient as it is an energy converter, not a voltage dropper.

Both will work, 7805 is cheaper but at the cost of heat and wasted power from the batteries

You can but I really would not recommend that

Not if you value your run time and keeping things cool

You will be dropping 7V across the regulator at 1A (Example), this is 7W thrown away vs only 5W consumed by the Galileo

Total 12W dissipation with 5W used. That’s a lot of wasted power and heat

The Buck Regulator will be close to 90% or more efficient vs ~40% for a linear regulator in this scenario

To specifically answer your question. Yes you could use a linear regulator like a 7805, it will get quite hot.

sir i wanted to interface my webcam with intel galileo ...howcan i do that...?

and wanted to perform some image processing on it...so please help me where to get started with...?

and i am new to Linux environment...!

i don't know much about building linux images ...!
