i see this one is on my arduino motor shield.
here is a link to the beefy version of the chip
http://www.mouser.com/Search/ProductDetail.aspx?R=L298Nvirtualkey51120000virtualkey511-L298
it seems pretty good and unlike the transistor H-bridge I have on my big robots this has no risk of shorting power to ground.
what i wonder though is if any of you know a cheaper chip that will get the gob done?
I need at least 1.5 amps preferably 2.
I am updating an old robot of mine to use a prop instead of the old 6502 SBC I used

    SparkFun has them for a lower price ($2.95).

    I like the chip myself. I'm using them in this project.

    Don't forget to get some Schottky diodes (you need eight per chip).

    thanks, thats almost half price.
    unfortunate though I already have an order ready for mouser and shipping will kill the savings unless sparkfun has good shipping prices.

    Code viper,
    SparkFun will ship small orders USPS if you request it.
