Freaduino UNO Released

By April 25, 2012 2 Comments

HI Guys, Freaduino UNO is released today. Freaduino UNO is an Arduino 100% compatible board. It is based on Arduino UNO Rev3 design. So you can use Freaduino UNO as Arduino UNO Rev3 . All code, shield and IDE for Arduino UNO Rev3 are also valid on Freaduino UNO . Some visible improvement on hardware make Freaduino UNO more flexible and easier to use.
For example: 3.3v or 5v IO selectable allow you connect some 3.3v modules (such as XBee) to Freaduino directly. SPI, COM and IIC bus breakout make bus connect easier, 800mA IO drive capability.


Freaduino UNO



  • Inherits all of Arduino Duemilanove’s features.
    Compatible to Arduino UNO/Duemilanove’s pin layout, screw hole and dimensions.
  • 3.3V or 5v Operating Voltage selecable
  • More visible location of Indicator LEDs
  • Wide range external input from 7~23V DC
  • UART/IIC and SPI interface breakout
  • Evolved with SMD components
  • Digital I/O pins 14 (of which 6 provide PWM output)
  • Flash memory 32 KB of which 0.5 KB used by bootloader
  • SRAM 2 KB
  • Clock speed 16 MHz
  • 68mm x 53mm
