This Uno R3 SMD, has most of the features of the Uno with the added benefit of an ISP header and CH340G interface. The UNO can be programmed over a USB B cable using the Arduino IDE: Just plug in the board, select “Arduino UNO” from the board menu and you are ready to upload sketches. You can power the UNO Board over USB or through the barrel jack. The on-board power regulator can handle anything from 7 to 15 Vdc.
