You can adjust the voltage by placing a multi-meter on the output, synchronously, using a screw driver to adjust a potentiometer. It can be minute adjustments to achieve a precise voltage.
Kindly reminder
These boards are adjustable current limiting, fixed 3A current limit.
Please make sure that this module within its working range before using.
Please don't output short circuit, otherwise the board would burn out.
When setting the parameter, please make sure output voltage is stable before using the module to avoid any possible damage.
Tips:
Please check if the product package is intact before opening.
Please check if the negative and positive terminals are accessed correctly before operating.
The input voltage should not be over 28 V to avoid damage.
Awesome product.

The distance between the output voltage terminals is slightly less than the holes in a standard breadboard. The device works otherwise.

I rebuilt 3 dome lights on a small boat with new switches and leds. I rebuilt each with two led and a 3 way switch - a 3v 3w and a 10v 10watt. My initial solution used resistors to drop the voltage but the resistors used too many watts so didnt see the efficiency gains i was expecting.I bought these to try a modern efficient led solution.First, it says 3amps but… that must be the max current it can ever see. I tried to drive an incandescent at 12.4v and 1.4 amps and the converter started cycling off after 25 seconds. I believe this is thermal cycling because converter was quite hot. Its thermal limited.I found best way to get this thing dialed is to use the incandescent load, multimeter on outputs then quickly adjust screw to desired voltage. Be warned you need a teensy flathead and must turn screw very very small amounts. I could only get within +/-0.05v.You must adjust quickly before it overheats.In my case i chose to undervolt the large led to 8.7v which was 0.7 amps, bright enough and converter stayed cool indefinitely.For my case these converters were very efficient. I wouldnt use with more than 0.9ampsIm quite pleased with this unit, who knows how long theyll last but power consumption in my dome lights are now much much lower. The low voltage bulb now draws 0.6watts.

As described. Works perfectly.

I haven't tested much beyond setting the voltage and forgetting it. I used it to create in all-in-one module for adding bluetooth to an older car stereo and it also powers a wireless charger. It has been stable and consistent for over a month now.I have read other reviews of input voltages exceeding the rating of the filter capacitor, so it's something to be wary of, but unfortunately there is no way to check the voltage rating of it so I cannot vouch for that.Love it overall, great package size, efficient and a wonderful value. Good to have in the bin for later projects.

It worked great when I tested one of them. So I permanently glued it to my setup. And now the potentiometer is not changing the voltage on 3 of them. I am pretty sure I didn’t turn it too far but who knows maybe I applied too much force. So just be gentle I guess. Giving it 1 star because the product was great when it worked. But didn’t even last a few seconds of adjustments.EDIT: I changed my mind. They are working really good now. Yeah the potentiometer can be finicky but it works. By trial and error you can get the right voltage. Just be careful to go really slow and gentle while changing voltage. Don’t push down too hard and turn slowly.

Out of 5, 3 of them weren’t working, the rotating screw hole to make the voltage lower do not work. For the 2 remaining, it works well and is stable, great alternative to the bigger buck converter if space is a concern.

It had the right pin pitch for a breadboard and the pot could be adjusted to get the right output voltage.

I got these to power a raspberry pi on my 3d printer. it was really simple to set it to 5.3v out on 24v in and it gets warm but not to a concerning level. voltage seems steady.Seems to be working great! cant wait to use the other 5 somewhere

I’m an Escape Room owner and have used these many times to reduce 12vdc voltage to 9v, 6v, 4.5v to power different escape room technical props/puzzles. I’ve also used to replace battery operated Halloween props like blow mold pumpkins using a 12v power supply and knocking down the voltage to replace the need for batteries. Cat5 wire or speaker wire works well, in a pinch, to accomplish this.As others have mentioned, adjusting voltage is a bit tedious and requires a small (tiny) screwdriver and it is somewhat hard to dial in, but it works with a little patience. Make sure your input power and polarity is correct or you will fire the circuit board. I tend to use a large heat shrink tube to enclose/protect the circuit board after hooking things up.

This device is small and adjustable to any voltage within the range specified, not just the discrete voltages listed. ie you don't select a voltage from a finite set of choices, you adjust it to anything you want in the range. Once set, it doesn't matter what the input voltage is, so long as it's within the specified range. At 3A rated output, it's perfect for mobile application payloads (eg. on drones), instrumentation platforms, and so on to name a few. At the low cost these devices sell for, I'm going to buy another batch just to have them around for those last minute projects that need a great stable power supply.

I have been using these converters for a while now and so far, they have been great. The potentiometer has it's pros and cons depending on your application but I do like the idea of being able to fine tune the output.CON: However, the main issue with this design is the form factor. The mounting holes will NOT line up with standard 2.54mm breadboard or pcb. You will need to bend some male header pins to mount and it works but it's kind of ugly.They are great for prototyping but I have no idea of long term durability.Just remember to set the potentiometer with a bench supply, multimeter and plastic flathead (I use the probe adjustment screwdriver for my scope) - once connected, if you need to make fine tuning adjustments, turn the potentiometer SLOWLY! If you do not need adjustable output, you might want to find a fixed output alternative.

Excellent adjustable buck style voltage regulators.. don't get hot, provide a soild voltage feed with raises and falls that stay within 1 to 2 hundredths a volt.. give a fairly clean output voltage (still need a LC filter if you want very clean wave forms) provides 0.6 to 23 volts from my testing.. able to pull a constant 3.5 amps off it at 16.8v without it getting hot 2.5amps at 20volts gets warm but ok... 3amps at 20v will cook the coil in about 20 minutes.. at 12v I was able to pull a solid 4.2a off it for 2 hours and the temp never got above 97F, 4.5a at 12v smoked it in 7 minutes...If you cook the coil on it it does NOT allow full voltage to pass through (I have had some buck regs fail and allow full voltage to pass through for a few seconds.. I killed two of these intentionally to make sure that when it failed no voltage pass through and on neither one did that happen and that makes me VERY HAPPY. A failure acts like a breaker, it fails it fails and circuit is instantly broken.. I tested this with a O-scope and it had 0ms of full voltage seep when it failed..) These are incredibly cheap and excellent quality.. over preform and stay dang steady.. These are without a doubt the best cost to preformance ratio bucks you can buy...Bucks are not a place to skimp and buy as cheap as possible BECAUSE a failure on a buck that is supplying constant regulated voltage to high dollar electronics and fail and allow unregulated voltage to seep by for even a 1ms can damage sensitive to voltage electronics and ruin your day and make you wish you wouldn't have saved that 30 cents per piece.
