Arduino UNO REV3 with microcontroller ATmega328 100% Compatible with USB cable


The Uno is a microcontroller board based on the ATmega328.

The board is equipped with 14-pin digital input / output (6 of which can be used as PWM signals), 6 analog inputs, a 16MHz quartz, a USB connector, a power jack, a connector for the ICSP programming and a small button to reset the card; also provides all that is necessary to support the operation of the microcontroller.

To start using the Arduino UNO is simply necessary to connect the card to a PC via a USB cable, or power the board from an AC-to-DC adapter or through a simple battery.

The Arduino Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial chip; Arduino UNO R3 board in fact implements the ATmega16U2 chip (which replaces the chip Atmega8U2 of previous reviews) planned just to be a USB-to-serial converter.

The Arduino UNO will be one of the future versions of the Arduino reference cards. The Uno is the latest in a series of USB Arduino boards, and is a reference model for the Arduino platform.
