This includes Overview | Power Supplies | Adafruit Learning System What is a power supply? A power supply is a device that supplies power to another device, at a specific voltage level, voltage type and current level.For example, when we talk about a 9VDC @ 500mA power supply can provide as much as 500mA of current and the voltage will be at least 9V DC up to that maximum current level. While it sounds simple, power supplies have a lot of little hang-ups that
