INTRODUCTION

   BUONO UNO R3 is an Arduino compatible board, It’s based on Arduino UNO R3 design, So you can use BUONO UNO as Arduino UNO, All Code, shield and IDE for Arduino UNO R3 are also valid on BUONO UNO, Some visible improvement on hardware make BUONO more flexible and easier use , For example: 3.3V or 5V IO selectable allow you connect some 3.3V modules (such as XBee) to BUONO directly.

 

FEATURES

   Inherits all of Arduino UNO’s features

   Compatible to Arduino UNO/Duemilanove’s pin layout, screw hole and dimensions

   3.3V or 5V operating voltage selectable

   More visible location of indicator LEDs

   Evolved with SMD components

   Digital I/O pins 14 (of which 6 provied PWM output)

   Flash memory 32KB or which 0.5KB used by bootloader

   SRAM 2KB

   EEPROM 1KB

   Clock speed 16MHz

   Micro USB connection make the cable can be mixed use with most digital products such as cell phone

   5V DC/DC provide 95% efficiency

   6V to 23V width rang input
