Description of Arduino Uno R3 Microcontroller A000066 from ARDUINO
We are proud to stock the brilliant Arduino Uno R3 Microcontroller A000066.
With so many available recently, it is wise to have a name you can recognise. The Arduino Uno R3 Microcontroller A000066 is certainly that and will be a great purchase.
For this price, the Arduino Uno R3 Microcontroller A000066 is highly recommended and is always a regular choice with many people. ARDUINO have added some nice touches and this equals great value for money.
This is a genuine new Arduino Uno R3. The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. Note From Arduino Founder Massimo Banzi We stress the fact that [genuine Ardunio board from mp3Car.com] are made in Italy because in this globalized world, were getting the lowest possible price for products sometimes translates into poor pay and working conditions for the people who make them, at least you know that who made your board was reasonably paid and worked in a safe environment. (This obviously applies only to the boards marked "made in Italy", we cannot attest to the manufacturing process of "third party" boards). The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Revision 3 of the board has the following new features: 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin that is reserved for future purposes. This is the org version of this product, not the CC.
