Thread: Power requirements for Motherboard and Processor

  1. #1

    Default Power requirements for Motherboard and Processor

    For a hobby, we're building a robot with a motherboard+processor combo. I would like to know how much voltage and current these two components would draw? And also, (consequently) please recommend a suitable battery rating.

    Please help! Thanks in advance

    This will help you out for sure.


    *If you want more help then post the details like the kind of components you are going to use and the kind of work the robot is going to do.

    Sorry! We're building a robot that would be completely controlled by the internet. Simply, we're planning to put a processor (Intel P4) and a suitable motherboard on board the robot, using a pen drive for the hard disk. Now we'll plug in a Wireless USB modem into the one of the USB ports of the motherboard so that the computer becomes internet-enabled now. Next, we'll be running an application written in VB6 that would control the motors in my robot (2 DC motors for the drive and 1 stepper motor for webcam rotation) through the parallel port. A portable client application would also be developed that would connect to the application ON the robot through the internet! With it, I would be able to control the movement of the robot and its camera.

    I would like to know how to power the motherboard and processor. How do I find out how much current and voltage is required for this? Also, as I'm skipping the SMPS, what kind of regulation would be needed? And how do I do it? Please help

    Use a TCP/IP card along with your controller board. The controller may be any 8 bit controller, if you dont do much - (like image processing).

    You dont have to add a motherboard just because you want the bot to be internet enabled.

    You have numerous options, just search for embedded ethernet boards.

    have not worked with rabbit, but this one looks interesting..

    if you are a microchip guy,

    (you might need an explorer 16 board)

    but all these ARE less costly and less power consuming than a normal motherboard.

    or, search for ATOM boards from Intel.
    .... I didnt do it ! ....

    Thanks! But I would not like to have a WiFi server lying around. I'm looking for plugging in the WiMAX modems that are now commercially available (like the Reliance and TATA Indicom ones). Would your suggestions support that!?

    Thanks a lot man. Please help me with this

    Easiest way to escape computations..... Anyways space doesn't look a concern for you as you are going to put a full fledged motherboard on your robot.

    So in that case buy a 200W SMPS and put a fully charged UPS on board. 1KVA UPS would be able to run this system for half and hour atleast! If you want more, put extra batteries in parallel :-)

    This is the easiest solution I can think of

    Space - not a concern. But the weight!! An UPS is gonna weigh a LOT! How much current and voltage would my two main components (motherboard & processor) need?

    You may borrow a laptop from your friend or from your college.
    If you cannot arrange a laptop, you can try to arrange for 2nd hand motherboards. To power them you may can use DC-DC converters.

    You may find readymade DC-DC converters, mini-ITX boards at http://www.iride.in/
