Freaduino AC UNO Support AC/DC Input MB_ACUNO (EF-01017)

Freaduino AC UNO is an Arduino compatible board. The first arduino board support AC input.It's use a 680uF electrolytic capacitors for filtering. The AC UNO support 5V-9V AC and 7V-22V DC. Output recommend 500mA Max.  It is based on Arduino UNO Rev3 design. So you can use AC UNO as Arduino UNO Rev3 . All code, shield and IDE for Arduino UNO Rev3 are also valid on AC UNO. Some visible improvement on hardware make Freaduino UNO more flexible and easier to use.  For example: 3.3v or 5v IO selectable allow you connect some 3.3v modules (such as XBee) to Freaduino directly. SPI, COM bus breakout make bus connect easier.
