Uno Rev3 A000066

The Arduino Uno Rev3 (A000066) is a versatile development board that serves as an excellent starting point for anyone looking to delve into the world of electronics and programming. Equipped with an ATmega328P microcontroller, this board provides 14 digital input/output pins, 6 analog inputs, and a USB connection, making it easy to connect and control a variety of components and sensors. Its user-friendly design ensures that beginners can quickly grasp the essentials of coding and circuit design while also offering advanced users the flexibility to create more complex projects.

Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), 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 a 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 Uno 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of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.
