product description
The Arduino Uno R3 (Revision 3) is an open-source microcontroller board that serves as the "brain" for countless electronics projects. It features everything needed to support the microcontroller: simply connect it to a computer via a USB Type-B cable or power it with an AC-to-DC adapter or battery. It is famous for its standard "Uno" footprint, which is compatible with hundreds of "shields" (expansion boards) that add functionality like GPS, Wi-Fi, motor control, and more.
