Arduino Compatible SMD UNO R3 AVRmega328P-PU Development Board

Description

Arduino Compatible SMD UNO R3 AVRmega328P-PU Development Board Controller With USB Cable

Feature:

Using ATmega16U2 instead 8U2 as USB-to-Serial converter, but does not mean its 16K Flash would make your R3 more faster, it is just serving for USB port
Added SDA and SCL pins for TWI communication placed near to the AREF, but just the copy of PIN4 and PIN5
Two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board, the second one is a not connected pin which is reserved for future purposes
Stronger RESET circuit, more stable, more convenience
