Ok well slight lie. There's one output and it controls some LED strips but its so far from anything I dont think it's too big a deal.If you don't use any of the outputs from the microcontroller, then what in the world is it doing?? Surely it must be doing something...
I wouldn't use those converters as power sources for analog circuits if I were you. Those are switch mode power supplies and are extremely noisy and will make it difficult to get clean signals from your analog components. It's best to use a linear type power supply for analog purposes. Even an old fashioned 7805 (properly filtered) is a better choice.
Ah ok interesting. So what's actually going on inside them? I thought it was just some coils - sort of like a transformer - that allows for power to flow through but means both sides are isolated.Be very, VERY wary of those things, especially the cheap ones. They can produce huge amounts of noise on both the output and input pins, and if you don't use them correctly they can easily make things worse instead of better.
