10Pcs Mini360 Buck Converter 3A DC Voltage Regulator Step Down Power Converter Module 4.75-23 V to 1.0-17 V DC-DC Voltage Regulator 3A Power Supply for DIY Portable Power Communication Equipment

I am in love with these little things. I use them all the time in projects and I have never had one fail,and I am an expert on releasing the magic smoke from electronics?.These modules are also incredibly small,which makes them great for projects where space is a concern.One down side I can think of is the little trace you have to cut to use the fixed voltages.It's extremely tiny and pretty tough to get at, I have stabbed my finger on at least two separate occasions with an xacto knife trying to get at it?. ( you need to cut this trace to use the static voltages, it took me a minute to figure out why the voltage output was off, so I thought I'd mention it in case someonje else missed it too.)The En pad is pretty nice too, makes it easy to turn the regulator off to conserve power.I am always really happy to find a component that has had a lot of thought put into it's design.Anyway,although these aren't quite as small as a LDO, they are still very small and can put out a lot of current without getting hot, these are definitely a great module to have in your parts bin.

These work great for a esp32 project I am working on. Keep in mind, these are designed to used the adjustable pot by default. If you want to use the fixed voltages then you need to break the trace right above the adj pads. There are two dots, break the trace between them.

Ordered the 5V version. First one I wired up output 12V and fried the ESP32. Second one was set for 1.8V, and couldn't get it to output 5V precisely -- it wavered between 5.5V and 4.5V and was a noisy mess.
