Arduino Uno R3 with Cable

Arduino Uno R3 Development Board with USB Cable

The Arduino Uno R3 is the quintessential and most widely used microcontroller board in the Arduino family. It is based on the ATmega328P high-performance, low-power AVR microcontroller. The R3 iteration features several hardware improvements, including the use of an ATmega16U2 for USB communication (instead of the older FTDI chip), improving compatibility and speed.

Designed for easy use by beginners and professional engineers alike, the Uno R3 is the foundational tool for learning coding, electronics, and physical computing. It operates at a 5V logic level with a 16 MHz clock speed. Power can be supplied via the USB connection or an external power supply connected through the barrel jack, accepting a wide input range of 6V to 20V DC (7V to 12V recommended). The board is highly robust, featuring short-circuit protection and a resettable fuse. It offers substantial connectivity, including 14 Digital I/O pins (D0-D13) with 6 dedicated PWM outputs and 6 Analog Input pins (A0-A5).
