    Solidly built dual input dual rail supply

    posted by xephris on 07/23/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    - Solid and stable regulated power supply from ~12V or 5V to 3.3V/5V - Runs cool - The 3 pins on each rail for GND and 3.3V/5V are nice - 3.3V/5V switch is secure and makes it just easy enough to change but hard enough to accidentally screw it up
    Cons:
    - Lack of an on/off switch - The mini-USB port only uses the power pins, it doesn't "talk USB", so drawing more than ...

    Very handy for projects

    posted by alepg on 03/28/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    It is very easy to use. You can select 5V or 3.3V on one rail with the switch, and the other rail is always 5V. Very useful in projects that need both voltage levels. A red LED indicates it is on. Mine is exactly like the one in the photo, and occupies very...
    Cons:
    It does not have a power on/off switch. You will have to unplug the USB cable or the DC plug.

    Not exactly as pictured, but perfect for me

    posted by thejcs on 02/23/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    It's a really piece, well made, beautiful and really useful. It has indepent voltage selectors for both sides , so you can have 3.3V on the left and 5V on the right side. There is an internal voltage converter.
    Cons:
    The board is different from the image, it covers some rows of the bread board. Instead of jumpers, it could use some switches f...

    just pretty peace of hardware

    posted by f11lbert on 02/01/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    Just love it - very simple and convenient solution. You can power on it from usb or from power adapter (or even from battery if you want and have adapter cable for that - from 9v battery to 2.0 connector). You can easely get power from socket on the board ...
    Cons:
    It is not like as on picture. It is a shame dx.com do not correct the picture after so many reviews about that. I reality it ha...

    Essential for Breadboard

    posted by mdma1g on 11/16/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    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.
    Cons:
    Mine is not like the one on the photo, It is rectangular and occupies prototyping space on the breadboard.

    Good for development

    posted by gadman on 11/07/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    It get's the job done. The top and the bottom pins can be changed separately to +5V or +3.3V, so you can use it to power 3.3V Display and 5V ICs at the same time. It fits perfectly on the breadboard. It has a on/off switch so you won't need to unplug the ca...
    Cons:
    Mine was different than the one in the picture. It has a rectangular shape and after you put it in the breadboard it takes away...

    Good buy if you need to use USB power on your breadboard

    posted by Aireal on 10/24/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    Can use both 3.3 and 5 volts at the same time. Just had to figure out how the jumpers work. (Not to hard, but no instructions) Takes both USB and barrel connectors although never connect at the same time!
    Cons:
    A little tricky to figure out how the jumpers work, but this is a minor issue. I would still recommend it, for the price.

    The best friend to your breadboard.

    posted by procchetta on 08/01/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    5v to 3.3v to power almost any project. Good design, one must consider jumper settings according to your needs. It is very practical to have all voltages directly from the module. Works with virtually any DC power supply. The POWER provided by the module is...
    Cons:
    In some microcontroller projects was necessary to place a power supply with a good filtration. Surely not a module problem but ...

    A upgrade, perhaps?

    posted by milliwhat on 06/01/2012 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    What I got was rather different to what's in the photo here. Perhaps you will too. I've uploaded pics, but they're taking ages to show up. But I think it might be an upgrade. Essentially, it's the same thing, a breadboard-able power supply. The input is v...
    Cons:
    The USB socket is a female A, the same as you would find on your computer. So to power it *from* the computer, you will need a ...
