## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I'm very pleased.
  

*by G***R on Reviewed in the United States on April 7, 2016*

I bought this DC step down variable voltage regulator to use in a Bluetooth 2.1 wireless speaker system project. The unit is specifically being used to step down a 24v DC power supply (who's main purpose is to power the 2.1 amplifier) to 5v to power a Bluetooth receiver. It powered up off the 24v power supply with no problem. The initial voltage output appears to be set to maximum (mine was outputting 24v, the input voltage). I began adjusting the voltage as indicated on the board and the output slowly decreased to 5v. The adjustment is smooth and not overly touchy. Once the voltage was set, I used it to power the Bluetooth receiver. The voltage output remained stable during my testing. I used earbuds to listen to the output of the receiver (don't have the 2.1 amp yet), and the sound output seemed as clear as when I powered the Bluetooth receiver from a battery (no line noise). I'm not an electrical engineer nor do I have any test equipment more sophisticated than my multi-meter, but based on my observations, the unit is performing perfectly for my needs. I'm very pleased.

    What you need
  

*by A***R on Reviewed in the United States on December 31, 2020*

I ordered this for a project that I am doing. It puts out 5v to everything that I needed. I ended up buying another just because of how well it worked and how much I liked it. Very small is pretty well built. My son is not good at solderign and this held up great for a first time soldering. Even when splitting out to multiple components that need the voltage, it works great.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works perfectly for applications where you'd rather not have a static readout of the voltage.
  

*by R***S on Reviewed in the United States on November 3, 2016*

Most of these DROKs seem to come with the big digital voltage display, which is probably very handy for use on a bench but unecessary and wasteful in an installed/embedded application.  This little board let me piggyback an esp8266 at 5v on an existing 24v source that's already in the location, to add wifi control to my ancient garage door's radio-control receiver.  Approximately $25 all-in to retrofit a garage door opener I can use from the phone in my pocket that also lets me see if the door is open or closed from anywhere in the world (thanks to a reed switch) is great and all, but one of my favorite parts of the project is that I didn't have to run a dedicated power line across my garage ceiling and down a wall to a permanent wall wart to get it up and running.  I will definitely be buying more of these in the future.
