  • Essential for Breadboard

    posted by mdma1g

    It's small.You can power it you can feed it via USB or via barrel plug, it has a jumper for voltage selector between 3.3 and 5v.I test it with a multimerter and works really nice.
    I want to know the quality of the components used and its strength and durability, but that's a mystery...
    I think these feeders breadboard are most useful when feeding our prototypes. As always we can buy some more expensive and maybe better but for this price, what can go wrong?
  • Really small!

    posted by Polonium

    This is a really small switching power supply!!Line side has a varistor, thus some kind of surge suppression is provided.Output voltage: 5.10V (no load)When no load is attached, a witched power supply draws about NOTHING current. Ideal green replacement for those old bulky transformers.
    Still didn't measure ripple at maximum load (will put results soon), but according the specs it is around 150mV (according the specs it is 150 mW, but that is probabely a bug...)
    Nice, cheap and small switching power supply.Not worth making one youself......
  • good product

    posted by fnflores

    good quality product, great luminosity (please take care, do not see LED directly), easy to use, it is applicable for any Arduino LED project, it comes with a standard packing.
    Recommended for high luminosity LED projects (I did a Christmas light for home), also to test any Arduino library works fine!
    Use it! it is fun and really easy to use!
  • not enough power

    posted by PKastl

    It´s a nice little module and emmidiatly ready to use.
    It offers really high voltages but the module is not able to bring the promised power.And it´s not possible to limit the current. no matter how you trimm the pot, its giving any current it likes
    all in one it is a nice little module if you don't wait too much of it.
  • Quick 3.3V regulator modules

    posted by realblades

    Works. Small ready to run 3.3 V regulator for microcontroller or other logic. Known chip with good data and clear markings. Decent looking board.
    LED and pin headers are not needed for a lot of uses but they're easy enough to change. There's no mounting points, but removing the pins and/or gluing something to the back works.
    Simple way to get regulatred 3.3 V for prototypes quickly so handy to have around.
