    I plan to do development with it on a Raspberry Pi 4 as shown in the short clip.

    It did not work from the get-go. Being returned

    this is the real arduino, the best thing about it is that it connect to the computer via a micro usb cable witch is the most common usb cable, and its the same size of the arduino uno so all uno shield would fit on this leonardo.....

    I bought mine from Mp3Car Store as other users stated that this seller provides genuine Auduino products. Other users were right. Im so glad that I could find the discontinued Leonardo at a good price as my project required the Leonardo specifically. Thanks

    Genuine Arduino shipped, but never connected through USB (on board programmer issues). Had to use ICSP headers and a separate programmer in AVR Studio to get code onto it.

    Works perfect

    $35 Leonardo board. Its a great board, no complaints, but if I had to do it over again, Id but the $25 UNO board.

    What can I say? This is the real deal, and not one of the cheaper knock offs. If you need an genuine Arduino Leonardo (with headers), this is what you are looking for.

    Do yourself a favor and buy from the actual Aurdino Site.

ABOUT ARDUINO

Arduino is the world’s leading open-source hardware and software ecosystem. The Company offers a range of software tools, hardware platforms and documentation enabling almost anybody to be creative with technology.

Originally started as a research project by Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis at the Interaction Design Institute of Ivrea in the early 2000s, it builds upon the Processing project, a language for learning how to code within the context of the visual arts developed by Casey Reas and Ben Fry as well as a thesis project by Hernando Barragan about the Wiring board.

WHY ARDUINO?

Why1Why1

Why2Why2

Why3Why3

Why4Why4

Inexpensive

Arduino boards are relatively inexpensive compared to other microcontroller platforms. The least expensive version of the Arduino module can be assembled by hand, and even the pre-assembled Arduino modules cost not so high.

Simple, clear programming environment

The Arduino Software (IDE) is easy-to-use for beginners, yet flexible enough for advanced users to take advantage of as well. For teachers, it"s conveniently based on the Processing programming environment, so students learning to program in that environment will be familiar with how the Arduino IDE works.

Open source and extensible software

The Arduino software is published as open source tools, available for extension by experienced programmers. The language can be expanded through C++ libraries, and people wanting to understand the technical details can make the leap from Arduino to the AVR C programming language on which it"s based. Similarly, you can add AVR-C code directly into your Arduino programs if you want to.

Open source and extensible hardware

The plans of the Arduino boards are published under a Creative Commons license, so experienced circuit designers can make their own version of the module, extending it and improving it. Even relatively inexperienced users can build the breadboard version of the module in order to understand how it works and save money.

Message from Massimo Banzi - co-founder

“The Arduino philosophy is based on making designs rather than talking about them. It is a constant search for faster and more powerful ways to build better prototypes. We have explored many prototyping techniques and developed ways of thinking with our hands.”
