DROK Buck Converter 24v to 5v, DC 4-32V to 1.25-30V 3A Adjustable Step Down Module, LM2596 Voltage Regulator Board, 12V to 5 V LED Power Supply Transformer

Works perfectly! Easy adjust, bright display, shows voltage in, voltage out, and AMPs out when connected devices are turned on. I'm using a 19.5 VDC 6.3 AMP power supply going in, and converting down to 7.2 VDC with one DROK LM2596 and down to 6.0 VDC with a second one at the same time. The 7.2 VDC powers a 4-servo controller and four servos. When I operate all four servos it displays the AMP draw way under the rated 3.0 AMPS, and the servos work steadily and smoothly over a 50 foot CAT6 cable over sending and receiving boards. The 6.0 VDC powers LED lights and show a steady 0.8 AMP draw when turned on. At the same time, I'm intermittently operating three DC motors directly from the 19.5 VDC supply; the servos remain steady, the LED lights stay bright, and the output display on both DROK LM2596 -- while set to display either VDC or AMP output -- remain steady as well. Conclusion: Taking into consideration the design/engineering/testing/development costs involved, the cost of each individual component on the module, the manufacturing cost, etc., the DROK LM2596 offers great value and performance within the price range. Five Stars plus Awesome!

Using this on my Ender-3 pro, connecting to a Noctua NF-A4x10 for the cooling fan.It was kind of a hassle, for myself, to connect but that's only because I have extreme OCD and need everything to look great. Almost manufactured if you will. Anyways, it works fantastic. Easy to control. Screen is easy to read, even in the sunlight (if you for some reason are using it in such a bright bright setting).The ease of install completely depends on how you want it setup. Me, as previously stated, made it more complicated than it needed to be. However, I've seen installs that still looking amazing that would still be considered easy.Works great though. Perfect product for dropping fan RPM's for certain filaments. Adds another level of control which is always nice.

The buck converter reduces a 12 volt dc input down to 1.5 volts as i needed for my project and it is within .05 volts according to an accurate multimeter. Finite adjusting of the potentiometer narrowed the output down to within .02 volts of 1.5. I am pleased the drok works but I have yet to assemble the project to determine how long the device will last under load. I would recommend this buck converter to anyone attempting to assemble a low voltage, low current project.

Just received my board today. Input voltage reads correctly on the display and matches output voltage. However, reduced voltage to 7 and hooked up a meter, which read 7.2. Adjusted screw with meter on and got to 7 with display reading 6.8. All In all a good product. Voltage holds steady through power cycles, doesn't spike on power up and holds setting when power is disconnected. If you're using sensitive low voltage equipment I'd recommend testing the output voltage on a meter before hooking up your device though.

My project called for distributing several different voltages from a single project box. My power supply to my project box was initially 12 VDC with a power rating of 80 watts. I was initially not planning on the addition of the buck converter for the 12 volt output I desired. Then upon testing (without a buck converter), I found that at working current levels, my voltage dropped to about 11.6 VDC. So I replaced that input power source with 15 VDC (power rated at 90 watts) and then regulated that down to my output voltages...12.2 VDC (with this buck converter)6 VDC (with a different buck converter with preset voltage)5 VDC x 2 (with 2 USB power converters)I dialed in the 12.2 voltage on the DROK unit and it stays there rock solid at my preset voltage. I compared the voltage with a portable volt-ohm meter and it is stable within 0.05 volts. I tried different current loads and the DROK remains stable at the preset voltage, even with different loads.I am very impressed with the stability, and reliability (through multiple power-on and power-off cycles and multiple days of burn-in time). The adjustment potentiometer has a lot of resolution and requires multiple revolutions to extend to the entire range. I was so impressed, I ordered a 2nd unit to have on standby.

Product is well designed, well built and works as advertised. Mine came with a few of the LED elements dead. Not a problem for my needs but something to consider as you shop around.

Got this buck to turn some power tool 20v batteries into 14.4v power for some electronics. Works very well for that. The digital read-out is very nice. there is a separate line-out power button so you can verify the set voltage before enabling the output. Once I adjusted the output voltage, it has held it across multiple uses. Small and nice features. Nice price.Already ordered more!
