The USB REG Board is a solution for powering your device over USB connection. It gives 5V directly from USB, but also features an MC33269DT power regulator circuit for creating 3.3V reference. The board is very small and can be integrated easily into your prototype or final product. The connection pads are unpopulated, so you can decide how to connect the board to your system. Male header pins are provided that you can solder, for typical breadboard use.
