Arduino Uno R3 - Original Q2 C1

The Original Arduino Uno R3 board is equipped with a USB connection, a power jack, an ICSP header, and a reset button. This comprehensive setup includes everything needed to support the microcontroller. Users can easily connect it to a computer via a USB cable or power it with an AC-to-DC adapter or battery to get started. The board is designed to be robust, allowing users to tinker without worrying about damaging the hardware. In the worst-case scenario, the chip can be replaced for a few dollars, making it a cost-effective solution for prototyping and development.

Named "Uno," meaning "one" in Italian, the board marks the release of Arduino Software (IDE) 1.0. It is the first in a series of USB Arduino boards and serves as the reference model for the Arduino platform. The Uno board and version 1.0 of Arduino Software (IDE) set the standard for Arduino development, which has since evolved into newer releases.
