FAQ:

Q: What is DC DC power supply?

A: A DC power supply is a device that supplies electric energy of fixed polarity, either positive or negative. “DC” in this context means “direct current.”. Direct current is an alternative to alternating current, frequently shortened to “AC.”. Power supplies take energy from a power input and deliver it to a power output.

Q: Can I use a 9V?

A: The quick answer is yes, you can. The long answer is yes, but only if your goal is to chose the most expensive and short lived batteries possible. 9V PP3 battery (Ashley Pomeroy, Wikipedia) I think the boards and documentation should have an explicit warning about 9V PP3s for this reason!

Q: What is a DC power adapter?

A: A power supply for electronic devices. Also called an “AC adapter” or “charger,” power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop.
