Any good tutorials on selecting power sources for IoT devices?

I’m looking for a good tutorial on supplying power to boards. For example, lets say you have a board that describes its power requirements as: Module working voltage is DC 8-26V, can be powered by 12V, 24V

What does this mean? Obviously you will use a DC power supply, but what about other parameters?

Can you test the module with a battery (or series)? Can supplying a voltage that is too low, hurt the board?

Should power supply be regulated/unregulated?

What about amps? Some power supplies specify amperage, but what if your board doesn’t specify?

I know this voltage example is probably high for IoT boards but the principles should be the same.
