How to power up intel galileo with a battery

Former Member

Sir i am using the intel galileo board which supports arduino 1.5.3 IDE. But in my project i want my robot moving with galileo on it.So how can i power up my galileo with a battery pack of 12v and the down convert it 5v and use it for galileo...plz help me

      ... Jamie, another thing to look at image

     

    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

     

    Regards

    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.

     

     

     

    Regards
