Funduino UNO R3


The Funduino Uno R3 is functionally identical to the the latest version of the extremely popular and easy-to-use open source Arduino Uno. The Arduino Uno R3 uses the ATmega328 microcontroller and features 14 digital I/O pins (6 may be used as PWM outputs) and 6 analog input pins. The Arduino Uno R3 can be powered through a USB connection, battery, or a wall power adaptor. This package comes with comes with a 2ft USB cable.

The Arduino Uno R3 uses the ATmega16U2 USB controller instead of the 8U2 found on the previous revisions of the board. It also adds SDA and SCL pins next to the ADREF pin, and the reset button has been moved to a more accessible location next to the USB connector.


  • Microcontroller: ATmega328
  • Input Voltage (recommended): 7-12V
  • Input Voltage (maximum): 6-20V
  • Digital I/O Pins: 14 (6 of which can be PWM outputs)
  • Analog Input Pins: 6
  • Clock Speed: 16MHz
  • Flash Memory: 32KB
  • SRAM: 2KB

Note: We'd like to point out that these are "compatible" Arduino Uno's. They are functionally identical, but are not the official boards manufactured in Italy.

Funduino UNO R3

The Funduino is a great alternative to the official UNO, at a great price and from the great people at Little Bird.
