FUNDUINO UNO R3 WITH USB CABLE ATMEGA328 COMPATIBLE ARDUINO

The UNO R3 is identical to previous versions and works correctly with all older Shields. This new revision has some extra pins. The SDA and SCL analog pins have been moved close to the AREF pin and 2 new terminals have been added after the RESET pin, one of which allows the Shields to adapt to the voltage supplied by the board. The reset button has been moved to the side of the USB connector. The ATmega8U2 chip has been replaced by the ATmega16U2, which allows us higher transfer rates and more memory. It is very popular and is used as a standard in classes and courses.
