    Good, nice and compact device. Very usefull in your own microcontroller prodject. You can set the output voltage very good. This output voltage is very stabel.
    On a lot of microcontroller and robotic prodject's I use this stepdown converter.
    I order a lot of them for other prodject's were I am working on. I am happy with this stepdown converter.

    RPM's increase fasterLights don't dim with my sound systemComes with all the required material to mount it
    If you know about the capacitors they have for sound systems, this is the same thing but for your other electronics. The components inside this device are water proof and comes with 3 extra grounding wires with mounting brackets. I have added a few pictures and hope that it will help with your decision in buying the product.
    A great product that help keep voltage at a constant level.

    This digital meter is great to determine the output voltage and current that is being supplied to your device. Seems accurate and dependable.
    I am curious to know how much power it consumes but is probably minimal. Nice size to keep in with other tools or USB adapters.

  • Great product for testing

    Good step-up module, with a clear display which display input and output voltage. Also you can turn it off (to save power). Welding is excelent and came with additional holes to fit it over a protoboard and M3 holes.
    I'm using this module to connect some bateries to make a regulable power source. I tested with a 550 mAh Li-Ion Battery and is working perfectly. Only have in mind the limitation of the board to 2.5 A.
    Great deal for DIY lovers!
  • Awesome, helped troubleshoot multiple chargers

    Very simple, appears accurate.I used it to troubleshoot multiple devices. I have a speaker wireless speaker that sometimes does not charge. By using this device I was able to tell that it does indeed charger, just the charging LED does not show.I was also able to test which chargers work best with which devices. My Galaxy Tab 10.1 only charges well with its own charger. I also discovered that one of my usb hubs is not a hub, but a charging splitter.
    Works like a charm!
    It's excellent nifty device! It's great to have on hand, especially with so many devices using USB.
