USES ATMEGA16U2 USB DRIVER NOT CH340 WHICH IS LOW COST Call for Price 0 in Stock Add Specifications, Prices & Availability may change without notice. Images are for illustration purposes only. E&OE Overview This is the new Compatible with Arduino ATMEGA328 UNO REV3. Uses ATMEGA16U2 USB Driver not CH340 which is low cost Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). 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.
