    posted by oozihemp

    Great power supply! -Comes with 2 individual channels, that can be set to different voltages.-Comes with a ON/OFF switch and a LED indicator.-Works with a bunch of power input options, surch as USB, 6V AA battery pack, 9V battery, 8.4V Li-Ion Battery pack.-Pretty decent Regulated 3.3V and 5V line, with just 2% of voltage drop.-Nice current output, 630mA usint a Li-Ion battery pack-Easy jump system to set the voltage or to turn the channel off-Easy to work with
    Its a great and well built power supply for small projects that needs a regulated power supply, works well with arduino or just powering normal DIY electronic project.
    It is a must buy product!
  • Solidly built dual input dual rail supply

    - 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
    Unlike some other reviewers, the board I received looks like the one in the picture. So I guess DX has corrected this since then.
    For this price and size, it's a decent power regulator.
  • Really small!

    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......
  • works well, good build

    Fits standard sized breadboards that are available everywhere. the ability to have a 3v3 and 5v rail is very very useful!I haven't tested the amount of current that can be drawn through this product however thus far i have had no problem. (tried with 2 servos, a small dc motor etc)nice that you an power it via usb or circular power connector
    If the power rails matched those on my breadboard it would be perfect
    Good little power supply but be careful of the lines and make sure they match with your breadboard in advance
  • Great little gadget

    The board is great. Powerful enough, it is small and compact switch mode power supply. I have used it as a LED stripe driver (for 1m of LED stripe) and as small audio system power supply. For the last one - it is very quiet, the EMI circuit does it's job. The holes make it easy to install.
    A very good and usefull SMPS. I really recommend it.
