This part works great, and it doesn't run hot like the linear converters as it uses an LM2596 step-down converter. I bought a few of these to try and get a bit more efficiency out of my battery packs rather than using an LM317 or any other linear converter. Will definitely get more of these to make sure I don't run out! Can't honestly think of any cons ... Read more
Good and compact little module.
Stable voltage even at currents above 2,8A.
Easy to adjust voltage quite precisely using the multi turn trim pot. 0,02V seems not to be a problem.
It doesn't get excessively hot. None, really.
A few holes in the PCB for mounting would have been nice, but double sided foam-tape works nicely too. You won´t regret having ... Read more
Quality components and does not run too hot. Output is very stable. Its a small form factor module and for the price you pay you cannot really do it yourself. The voltage ajustment screw is not tight enough for shocky environments. I use it in a offroad car and sometimes its a bumpy ride. I use this module in my car to power 2 usb ports that i have ...

The LM2596 is an excellent IC. The output is quite steady and clean. I'm using it with a pack of batteries to feed servos (5V) and the output remains around the same voltage throughout the life of the batteries. It may have a slight variation, but it's ok for common electronics. My unit came with a broken potentiometer. I desoldered the original and ... Read more
Efficient device with small form factor, looks like having good components It is a bit heavy (used on a RC model, so this is relative) and maybe a static voltage selector or a "lock" on the tuning bolt could help to avoid changing settings after tuning.
Get a bit hot but depends upon usage scenarios. Reasonable price for a good tool, used ... Read more
I used this in my Arduino project to reduce a 12 volt power circuit down to 10V. Worked perfectly and doesn't get very hot. Components are simple and well made. No manufacturing flaws None to report. Worked well in my circuit. Some pins were bent when I received it but not an issue. Could have had the voltage points (where you soldered) drilled out ... Read more
Easy to use, extremely handy to have around. You never know when your going to need to adjust a voltage! Great build quality. Simple to work with. Adjusting the potentiometer takes a few tries (pretty sensitive, use small movements) for me it does anyways. Go for the bulkrate and stock up, once you have them you'll start seeing applications for it all ... Read more
The module is inexpensive, but is very well built. It is super useful. I used it to build an iDevice charger by using a Nikon EN-EL3e 7.4V battery, and by adding 2 voltage dividers for the data lines. I was also able to use it to step down the voltage from car battery to power Raspberry Pi, a USB hub, and several other USB devices. none at all When ... Read more
the price is very cheap, and great quality, didn't have any serious cons, increases and lowers voltage very steadily, used it to control the voltage coming from a 24v power supply to a wiper motor, worked great. there is one small con, is that you need to turn the bolt a lot to increase and decrease the voltage it would be great if dx.com would bring ...

Easy to finetune with the precision potmeter (within a few dozen millivolts)
Simple to connect: two input terminals and two output terminals No extra holes in the print to attach it to somewhere (I ended up attaching them to my main print using the four input/output wires, making it "hover" above the main print, which worked well enough). ... Read more
