BELONG 1pcs LM2596S DC-DC Constant Current Module LM2596 DC-DC 7V-35V Step-down Adjustable CC/CV Power Supply Module

hey again and welcome back today I want to take a look at this module that I got in the last mailbag which I can link up there this is a constant current constant voltage adjustable buck module so that means you put a higher voltage on this end you get a lower voltage on this end and these pots here let you adjust that these things are commonly used to charge lithium batteries or to run LEDs you can also sort of use this as a benchtop power supply but the voltage will be a bit low on this thing it is a switching regulator so that means that the efficiency should be pretty high but it still can't output that much current so let's have a look at this it didn't come with any instructions and as I'll show you a little bit later instructions are kind of hard to come by on this thing but I figured a good place to start would be to take a walk around the device this is the input side on this s
