Other Variants of Arduino Board

For more advanced users, we do carry other Arduino Variants such as the Arduino Mega Board, which has a similar function to an Arduino Uno R3 but with more Input/Output (I/O) pins, or Arduino Nano, a compact version of the Arduino Uno R3 for those project with size constraints.

What makes the Arduino Uno R3 even more popular is the existence of Arduino shields, shields in general are boards that you place on top of the Arduino Uno Board for easier prototyping, without the hassle of using wires to connect each pin.

If you’re not sure on where to start we recommend the Arduino Starter Kit.

What is Arduino?

Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone projects or can be connected to software on your computer. The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
