[Discontinued] SainSmart UNO R3 Improved Version+IIC LCD2004+Sensor Shield V5 for Arduino UNO R3 Duemilanove Nano Robot

SainSmart UNO R3 is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega328-AU. 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 Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc. More 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. Controller uses SMD MEGA328P-AU chip. Add A6/A7 port. SainSmart R3 can directly use the electronic building blocks on I / O port and elicit G, V, S.The 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 R
