The Arduino Uno microcontroller module, designed and assembled in Italy,  is the brain of our popular Shield-Bot educational robots.  We offer it here as a replenishment item for our related kits. Our tutorial for the Shield-Bot robot, "Robotics with the Board of Education Shield for Arduino" and its assesment material have been certified as California A-G curriculum (see the Additional Resources tab below). In addition, we offer Arduino code for many Parallax sensors and accessories


  • Fits the Parallax Board of Education Shield
  • Based on the ATmega328P
  • 14 GPIO (6 PWM capable) and 6 analog inputs -see Details tab below for more
  • Programmable via Windows, Mac, and Chromebook*

Through an arrangement with Codeanywere and NICERC (the National Integrated Cyber Education Research Center), Parallax is offering Shield-Bot classrooms access to edu : Codebender, a Chromebook-compatible online programming tool for the Arduino Uno.  For details and to apply for a key, click here.
