LM2596-ADJ Power Supply Module

Quality item, used in several projects

Very happy with these, I have used them in several projects. easy to dial in the voltage, and they stay where you set them, minimal drift.

Excellent

I love these little boards! Very easy to use and can fit into almost any project!

Perfect

Works as expected. Larger than other that I have used but supports more amperage

Great for DIY!

Simple, and easy to use. Have a multimeter handy, and you're good to go. Voltages remain constant and consistent under light load. Looking down at the potentiometer, turning right increases voltage output (up to input voltage) turning left lowers voltage.

These work great for small projects of electronics

I use these for stepping down 12v to 3v for LEDs and other small projects. There is fine adjustments to dial in precise voltages. They were packaged nicely and have had no issues with them, work as described.

Easy to use

Adjustment is easy and accurate led onboard to indicate voltage in v- in and out clearly marked

Great price. Great performance

They work very well I used one to lower the voltage of a USB cable's 5V to 3V for a wireless headset that used AAA batteries.

Works well

I've used these 3 times now and they work as expected every time. I haven't have such

They work and don’t get hot.

Good little regulators. I use them to power LEDs from 5vdc to 3.5vdc. Arrived super fast.

First time, perfect results

First time using a buck converter, and it was simple to use and easy to adjust. I 3D printed some cases for these, and they fit right in and allow you to adjust without opening the case. Soldering was easy, they seem to run cool, have a power LED (though it is in my little 3D box) and I'm happy with the product and the project I used it for (wiring 12V LED strips into a 24V power supply).
