This Arduino® range covers the most widely used models on the market. Used in millions of personal, educational and professional applications, these boards benefit from an incredible amount of freely available resources (documentation, usage examples, schematics, source code, etc.) on the internet.
Most projects can be built with the Arduino® Uno, Leonardo or Mega2560. Applications requiring more resources and performance can be built with the Arduino® Due. Choose the Arduino® YUN Rev 2 for IoT applications, or the Arduino® Nano / Micro for size-constrained designs.
Arduino® software resources are freely available for download at www.arduino.cc
