Arduino UNO R3 [Compatible-Clone]

The first open-source microcontroller board made it easy for anyone who wants to learn electronics and programming or build something without getting a degree in electrical engineering or computer science.

Note: Arduino Compatible-clones have the same functions as the original board, and more or less the same performance. Due to Arduino technology being open-source material, a number of 3rd-party companies have took to adopting the technology and created compatible boards and selling them at cheaper prices than the original. We mark the compatible-clones in the listing as such without the Arduino logo.
