    Step up step down DC to DC changer. It works fine for a small loads such as ventilators or small DC motors or other electronics. Like it for my DIY projects.

    Arrived quickly and was well packaged. The module handles loads under 1A without any heat issues. I am using this on one of my quads for providing stable 12v for my gimble, works well for booth 3S and 4S batteries.

    Fast shipping and delivery. All modules are in the pack. I tested it and the product operates as described. Very useful, small enough and the price is really great. A good option for stabilizing my solar panel voltage or boost low voltage output of existing power supply modules to make them work in other applications. Very satisfied!

    I ordered three of these modules. I had never used them before, so I hooked them up to a basic adjustable power supply and measured the output while I made adjustments to the trimpot. I was having problems with the output voltage on the first one I tested, where it wouldn't go below 9.5V, even with a 5V input (I needed 3.3V). The step-up still seemed to work fine. I tried to figure out which component failed, but I never did. I even removed the trimpot for testing and resoldered a couple of surface

    They work great, I was impressed by the resolution of the trimpot and consistency of the voltage output. They have a wide range of input and output voltages and the current is enough for many applications.

    With a 12V power supply I achieve 1.75V to 47.5V output range, pretty good for the size and can easily be incorporeted inside any electronic project
