This Breadboard Power Supply Module plugs directly into a solderless breadboard and provides both 3.3V and 5V power directly to the breadboard power rails. The board accepts 7 to 12V DC input via the barrel jack or 5V via the mini-B USB port. It provides two regulated, fuse protected outputs which can be selected to be 3.3V or 5V. Male pin headers are available on the top of the board if you need to use flying lead connections. The board comes with a power indicator LED.
