Original Arduino Uno R3

 

Arduino Uno Rev 3 is a microcontroller board based on the ATmega328, an 8-bit microcontroller with 32 KB Flash memory and 2 KB RAM . It has 14 digital input/output pins (6 of which can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

Contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-DC adapter or battery to get started. The Uno board is the first in a series of USB boards and the reference model of the Arduino platform.

Arduino Uno is the ideal programming board to get started working with electronics with fun and practical projects. This board is your introduction to the unique Arduino experience: perfect for learning the basics of how sensors and actuators work, and an essential tool for your rapid prototyping needs. Arduino Uno Rev3 is the most used and documented board in the Arduino family.
