Original Arduino Uno Rev3 (A000066)

The Original Arduino Uno R3 Rev3, made in Italy, is an official microcontroller board based on the ATmega328P. It features 14 digital input/output pins (6 of which 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. This board 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. The Uno R3 also allows for faster transfer rates and more memory, making it a versatile and reliable choice for your projects.
