This Arduino-Compatible ATmega328P development board has all of the features of the original Arduino Uno with the added benefit of an ISP header and CH340G USB interface. This development board 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 ATmega328P Board over USB or through the barrel jack.
