[Discontinued] SainSmart UNO R3+ Sensor V5 + LCD2004 Yellow for Arduino UNO MEGA R3 Mega2560 Duemilanove Nano Robot

SainSmart Arduino Uno: Description:This is the new Arduino Uno R3. 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 Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc. 3.3VV/5V Supply Voltage and IO Voltage is optional. 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
