Original Arduino Uno Rev3
The board contains everything needed to support the microcontroller. Simply connect it to a computer with a USB cable or power it using an AC-to-DC adapter or battery to get started.
The Arduino Uno is beginner-friendly and robust. You can experiment freely without worrying too much— in the worst case, the DIP microcontroller can be replaced easily at low cost.
The name “Uno” means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno Rev3 became the reference model for the Arduino platform and remains one of the most widely supported boards worldwide.
