NEW PRODUCT – Arduino Uno SMD – Atmega328 – assembled. The new Uno is the latest version after the Duemilanove, with an improved USB interface chip. Like the Duemilanove, it not only has an expanded shield header with a 3.3V reference and a RESET pin (which solves the problem of how to get to the RESET pin in a shield) AND a 500mA fuse to protect your computer’s USB port, but ALSO an automatic circuit to select USB or DC power without a jumper! The Uno is pin and code-compatible with the Duemilanove, Diecimilla and older Arduinos so all your shields, libraries, code will still work.
This is the SMD edition, created during the Worldwide Atmel Shortage of 2011; Atmel could not make enough of the Arduino chip in through-hole format to fulfill demand. This UNO has an SMD version of the chip instead. It acts completely identically – all code and shields work perfectly – except you cannot remove the AVR microcontroller.
New! Each Arduino ordered from Adafruit now comes with 4 rubber bumpers that will help protect the board when you want to place it on a table. (Also keeps the Arduino from sliding around.)
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
