In addition to all the features of the previous board, the Uno now uses an ATMega16U2 instead of the ATMega8U2 chip. This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.\u003c\/p\u003e\n\u003cp\u003e3.3VV\/5V Supply Voltage and IO Voltage is optional.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eMore 3.3V modules supported, such as Xbee module, Bluetooth module, RF module, GPRS module, GPS module, LCD5110 Backlight and so on, but the original version can only support 5V IO.\u003c\/p\u003e\n\u003cp\u003eController uses \u003cspan style=\"color: #339ccc;\"\u003e\u003cstrong\u003eDIP MEGA328P chip\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eAdd A6\/A7 port.\u003c\/p\u003e\n\u003cp\u003eSainSmart R3 can directly use the electronic building blocks on I \/ O port and elicit G, V, S.\u003cbr\u003e\u003cbr\u003eThe Uno R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Uno R3 works with all existing shields but can adapt to new shields which use these additional pins.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #339ccc;\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e   ATmega328-AU microcontroller\u003c\/li\u003e\n\u003cli\u003e    Input voltage - 5-10V\u003c\/li\u003e\n\u003cli\u003e    5V Electric current : 500MA\u003c\/li\u003e\n\u003cli\u003e    3.3V Electric current : 50MA\u003c\/li\u003e\n\u003cli\u003e    14 Digital I\/O Pins (6 PWM outputs)\u003c\/li\u003e\n\u003cli\u003e    8 Analog Inputs\u003c\/li\u003e\n\u003cli\u003e    32k Flash Memory\u003c\/li\u003e\n\u003cli\u003e    16Mhz Clock Speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: #339ccc;\"\u003e\u003cstrong\u003eMain Changes from the older version:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e    TWI interface and the IOREF in the top and bottom connectors.This change keeps the board 100% compatible with the current boards and shields, but adds possibilities for new shields.\u003c\/li\u003e\n\u003cli\u003e    Reset button moved from center of board to corner near USB connector.
