The Uno r3 is a microcontroller board based on the ATmega328 chip from MicroChip. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz crystal oscillator, a USB Type B connection, a DC Power Jack, an ICSP header, and a reset button.

It 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 (you'll need one with a standard 5.5mm DC Barrel Jack connection) or battery to get started.

This is the latest revision of Uno and features stronger reset circuit and 16U2 microcontroller instead of the 8U2.

What you get:

  • 1 x Uno R3 Board
  • 1x USB cable

Features:

  • This board is a generic variant, built from the open source Arduino® Uno R3 design. It is a compatible replacement for the official Arduino® Uno, however, we recommend and guarantee that only the official variant will work with all Arduino® educational resources wherever it is referenced. Buying official also supports the creators and their future innovations.
  • Microcontroller: ATmega328 (datasheet)
  • Operating Voltage: 5V
  • Input Voltage (recommended): 7-12V
  • 2.1mm Centre-Positive Barrel Jack (Regulates Voltage from 7-12V DC) - The Uno will use any 7-12V source here, as long as it is connected center positive and is 7-12V DC. Here's a suitable Australian power supply.
  • Input Voltage (limits): 6-20V
  • Digital I/O Pins: 14 (of which 6 provide PWM output)
  • Analogue Input Pins: 6
  • DC Current per I/O Pin: 40 mA
  • DC Current for 3.3V Pin: 50 mA
  • Flash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader
  • SRAM: 2 KB (ATmega328)
  • EEPROM: 1 KB (ATmega328)
  • Clock Speed: 16 MHz
  • Note that the USB to Serial conversion chip is an Atmel MEGA16U2 which is the same microcontroller as the original Arduino Uno.
