This board makes it easy to connect and drop the voltage (not increase voltage). The design could be improved with the provision of a place to put a proper heatsink. It would be better to use the TO-220 packaged LM2596, as it provides a hole to attach it to, where as the current design To-263 provides none. You need to do this if you want to pass the full 3A capacity through the chip. The voltmeter on the board makes it useful to check the incoming and outgoing voltages, so you can see the output voltage you are adjusting. The mulit-turn pot is a bit fiddly and there is no indication when you get to either end. I used a old computer power supply as the input, so if anything went wrong it would still shut down.

I use LM2596 DC-DC converters to power several devices (mostly Raspberry Pies and 12V car monitors) from a single 12V source. It provides a visible health status (either input or output voltage, selectable by pressing a button) which is very convenient. Output voltage can be regulated and RPis operate best with 5.4-5.5V input.

Very happy with it. Adjustment takes a while to figure out which way to turn it to adjust but once you figure this out all is OK. Read out very accurate when checked with my precision volt meter
