Original Arduino Uno Rev3 A000066
This Arduino Uno is an original microcontroller board from Arduino officials based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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.. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
“Uno” means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Original Arduino Uno Rev3 board is the first in a series of USB Arduino boards and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

Frequently Asked Questions
Is the Arduino Uno Rev3 compatible with older Arduino shields?
Yes, the Uno Rev3 maintains the same shield-pin layout as previous Uno versions, ensuring compatibility with most Arduino shields.
Can I power the Uno Rev3 from a battery pack?
Yes, you can supply 7–12 V to the onboard barrel jack from a battery pack; the onboard regulator will step it down to the 5 V needed by the board.
How do I replace the ATmega328P chip if it gets damaged?
If the ATmega328P becomes faulty, you can purchase a DIP-28 replacement chip and swap it into the Uno’s socket, then burn the Arduino bootloader using another Arduino as an ISP.
