    The Quiz Showww!!!

    Lets start a funny game and see how much you all know about driver electronics .

    The final goal is guessing the specs of them all.
    a) Vin supported
    b) Vout delivered to led
    c) Current (mA) delivered to led

    Why to do that??? To have a funny time and.... errrr.. help a quite stupid guy who started buying bunchs of different boards in dealextreme and didn't write down their specs
    Now even in dealextreme they're not found heheh... who would that guy be ??

    Of course there's a price for each one correctly detailed... an enormous cold beer in Spain

    First Board




    Second Board




    Third Board




    Fourth Board




    That's it! Go for it!! Try to help that poor guy....

    Board four may be this......http://www.dealextreme.com/details.dx/sku.7612

    Think its only about 4.5 to 5 volts input

    Almost yes! it's almost exactly but I bet it's not the same... see the rear part in the dealextreme one and it shows "NANJ 13"... mine is "NANJ 15".
    Don't really know the exact difference

    Impossible to do that! Chinese drivers are not a quiz but a lottery!

    It's not impossible!! For example the forth one has 3x7135 circuits and each one provides around 350mA so that board is Ah out.

    Eeeeeeeeeekkkk !!! It's not! The kaidomain one has another piece of electronics which I don't know what servers for. The big one silver in silver... Another question regarding that board. Where must the positive and negative of the battery be connected?

    Really Really small and even a hot one (ueejjjjj). The upper board has this small peace of yellow electronics not found in my second board

    I don't see a top pic for #2, and #3 has some crazy looking soldering (not sure I would trust it without doing some cleanup). I have made a habit of printing the specs and any useful pics out on a small piece of paper and keeping it in the bag with the drivers due to the same problem you are having. Fortunately I was able to still locate all my drivers months ago when I went though them. Good luck!

    #4 is a 1050mA driver (3x7135 chips) and has modes (since it has a PIC). You can probably use the info from this one:
    http://www.dealextreme.com/details.dx/sku.6190

    Here is a customer pic - looks like yours:

    #1 seems to be the 3256 driver. There are "old" and "new" versions of this board, which look slightly different, and with sightly different specs. So it depends on when you bought these.

    They're speced at 3.7 - 9v input / 800mA output......BUT the old ones were not really happy above 6v and output was closer to 1A. The new ones reportedly can handle more voltage, but are putting out well over 1A.

    I've had good results with the older ones, ordered last October.

    These have been discussed here a lot....there is a way of bringing the output down by scraping the resistors....which seems like a lot of work for a $2 driver.

    mmm.....beeer!

    JZ

    EDIT: Yours is the "old" version......It looks exactly like the ones I have.
    It's not about speed, it's about lack of control.

    And another one getting the price! I hope paypal accepts it.
