Beyond expectations
It's the best Arduino for beginners and buying the original one instead of clone gives the quality that you expect for that money and functionality also

Product is good and genuine but...
Its a genuine product and works well. But the same board is available at much cheaper price in Robu. Almost 800 less. Why is it so expensive here?

Perfect quality and functionality
It's good and everything is good and assembly is very easy, the money may be a bit expensive but it still is a fair price, and the speed of it is good, and overall functionality is good.

Je possèdait une carte Arduino Uno, et je voulait me lancer dans le monde des objet connecté. Reçu rapidement, bien emballée, et fonctionne très bien. Je recommande !

Arduino Leonardo は、ほとんどが Arduino Uno と同じ構成で使えて、さらにパソコンに接続した状態で、マウスやキーボードの代わりにもなる便利なボードです。つまり、他のスイッチやハードウェアをつけなくても単体で遊べる範囲が多いのが特徴です。 Arduino を紹介した多くのページでは、Arduino を USBに接続すると自動的にドライバの組み込みがされるように書かれてますが、2/12にダウンロードしたIDE環境「Arduino 1.0.5-R2」+ Windows 7 の場合は、そうではなかったので、少し補足しておきます。参考になる人がいれば幸いです。 1.Windows 7 でのドライバのセットアップ方法 1.1 「Arduino 1.0.5」を展開したフォルダの「drivers」フォルダにある「Old_Arduino_Drivers.zip」を展開して、中にある「Arduino Leonardo.inf」を「drivers」フォルダの中に書き出します。 1.2 Windows 7 が 32bit版なら、dpinst-x86.exe を実行し、ドライバをインストールします。 64bit版なら、dpinst-amd64.exe を実行します。 1.3 そののちに Arduino Leonardo を USBに接続すると「Arduino Leonardo」がきちんと認識されるようになります。 2.ボード単体で遊べるスケッチ (サンプルコード) 「01.Basics」>「Blink」「Fade」で、ボード上のLED点灯を試せます。 「04.Communifation」>「PhysicalPixel」は、IDEの「ツール」>「シリアルモニタ」を開いて、H, Lという文字を送信することで LEDのオフ・オンをコントロールするデモ。 「05.Keyboard」>「Keyboard」>「KeyboardMessage」も同様にシリアルモニタ上で入力した文字を書き換えるデモ。 プログラムコードはシンプルなので、プログラムに振れたことがある人なら、誰でも簡単に動きを理解することができるのではないでしょうか。

This board is an excellent choice for custom projects that need direct USB communication. The ATmega32U4 chip makes it stand out because it can act as a keyboard or mouse without extra libraries, which opens up a lot of creative possibilities. With 20 digital I/O pins, 7 PWM outputs, and multiple analog inputs, there is plenty of flexibility for sensors, LEDs, and control devices. The headers are sturdy and make prototyping easy on a breadboard or with jumper wires. Running at 16MHz, it is fast enough for most hobby and DIY applications. Setup with the Arduino IDE was seamless and sketches upload quickly over USB. The board has been reliable during testing, and the small size makes it easy to embed into projects. A great microcontroller for makers who want more functionality than a basic Uno while still keeping full compatibility with the Arduino ecosystem

Al ser original te evitas quebraderos de cabeza debido a incompatibilidades, con otros equipos que te hacer perder mucho tiempo probando tus scripts, etc
