Arduino Uno SMD (Atmega328 – assembled) – Uno SMD w/Atmega328
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.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
