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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
