Friendly platform for electronics learning and prototyping. Arduino UNO R3 is the most popular board based on the Atmel AVR microcontroller. Use it to sense, respond and control the outside world with a large selection of sensors, and shields. Get started quickly with a large library of software and an easy to use IDE for Mac, Linux, and Windows.
The UNO R3 and UNO R3 SMD are 100% compatible. If one is out of stock you can use the other. The only difference is the type of chip package used in manufacture which is removeable in standard version.
