ok so i am making a robot and i need to control 2 12 volt motors but here is the problem i need to flash the code in to the board because of the design of my robot i cant fit my laptop in or on the robot can you help?????

    Help with the fitting in or the fitting on?

    Motor details?
    How much space is available for all this?
    Is this urgent?
    What sort of "control" have you in mind?

    control. on off
    as much as required

    So, pretty basic requirements.
    Maybe a BS1 or a BS2 for a microcontroller. The Propeller QuickStart has a small form factor. Which depends how much you know and/or want to learn.
    No motor details provided, but look at the HB-25 motor controllers to go with that.

    http://www.amazon.com/gp/product/B007HQE394/ref=olp_product_details?ie=UTF8&me=&seller= so this will work?

    That's a good price, but you'll need support electronics for the motor controlling.
    If it's truly a simple matter of "on/off" (based on some criteria, events, data) then you'll only need some transistors and resistors, minimally, to accomplish that.
    What are your expectations? What's the goal?

    well i need it to go in a large robot that just roles around but are you sure it can handle the 12 volts because it has spots for a 9 volt battery

    sorry i kinda new at robots

    The transistors will handle the 12V part.
    Again, you've provided no details regarding the motors.

    Sounds like you are "kinda new at" electronics, too.

    I cannot make solid recommendations without specifics from you.

    oh i am sorry this is the motor i will use because it can go fast plus it can cart a lot of weight http://www.amazon.com/Razor-e300-V1-V35-Motor/dp/B001TNOKF8/ref=sr_1_13?ie=UTF8&qid=1332722991&sr=8-13

    What is that, a 300W motor?
    I have the feeling that you'll want more than "on/off", you'll want proportional control, to vary the speed and so on, maybe even reversible direction.
    You may want to go with the Propeller for the microcontroller. I don't think Parallax offers a suitable motor controller.
    In a nutshell, the microcontroller supplies PWM to the motor controller for speed, as well as other control signals, and accepts related input (monitoring and the like); the motor controller handles the power electronics as directed by the microcontroller ("brain").
