Review: DUBAI - WE BUY THIS IN FEB AND WE TRY IT LAS WEEK BUT ITS NOT WORKING DEFECTIVE PARTS
Review: 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。

## Questions & Answers

**Q: Some say fake, some say genuine.  Which is it?**
A: Here is the problem, Amazon reviews are by the product name, not seller. So you will see reviews for both fake and real. If it's coming from China, rest assured it is a fake. If it's less than ~$18, it is most likely a fake. I purchased from mp3car store for about $19 and I received a genuine Arduino. Also keep in mind there are some legitimate clones that are perfectly legal, provided they do not use the Arduino name on the board - they may may use cheaper components (e.g. voltage regulator). But these ones on Amazon for around $12 are counterfeit since they use Arduino name and trademark and attempt to trick the buyer into thinking they got the real thing.It looks like Amazon has partially fixed the problem. Previously under "more buying choices" you would see the counterfeits. The tell tale sign was they were about $13. The have removed them, but you can still find them for sale under search term "Arduino Compatible". Amazon however should ban them from sale since they use Arduino name/trademark on board.Here is an example of a counterfeit board http://www.amazon.com/Development-Microcontroller-MEGA328P-ATMEGA16U2-Arduino/dp/B00G46X31W/ref=sr_1_11?s=electronics&ie=UTF8&qid=1392856538&sr=1-11&keywords=arduino+compatible

**Q: Does it come with USB connector?**
A: No, genuine Arduino units do not include the USB connector.  Some sellers are including USB cables with their 'knock off' boards, but selling them here on Amazon is against their terms of service.

**Q: how do I attach my USB plug to this board?**
A: You can use a Micro B cable to plug in this board.

**Q: it says have 20 I/O pin. but in picture, there are only 13, how to make use of the rest of IO?**
A: For the Leonardo, the AI pins (A0-A5) can be used as digital pins... See the Arduino website for more details. http://arduino.cc/en/Main/arduinoBoardLeonardo

*by C***N on 30 September 2025*

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
