  • Very useful module for prototyping

    posted by rgojko

    Perfectly fit on my breadboard. I'm using it in the combination with 12V DC power adapter for Arduino projects, and it's plugged into my breadboard ever since I got it. Good quality. Option of choosing 3.3V and 5V separately for left and right side proved to be very useful in my case. Even when I'm using power supply from Arduino board, it's still plugged in and has a function of bridge between left and right side of breadboard (of course, you have to choose the same voltage for both sides in that case)
    I really couldn't think of any other feature on this module that would be useful to have and that it's not already there.
    I'm extremely satisfied with this purchase
  • 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?
  • Switching Regulator

    posted by Logsplitter

    A simple device, no external components required. Output ripple is very low, as is heat as full output. No heatsink necessary even at continuous full output, (with 15 volts supply voltage).
    The regulators can be combined with steering diodes to increase output current. The ripple does not appear to increase even when combining the output of 3 regulators.
    An excellent stand alone regulator, especially for a USB power source. Have used more than a dozen for automotive cellphone chargers without a single failure
  • 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......
