Review: Arduino Uno Rev3（型番 A000066）は、電子工作の入門にも発展的用途にも十分応えるボードだと感じた。ATmega328P を搭載し、16MHz のクロックで安定動作。デジタルIOが14本、そのうちPWM出力可能なピンが6本、アナログ入力が6本と、センサー接続・LED制御・モーター制御など色んな実験で自由度が高い。USB経由でPCに繋ぐだけでプログラム可能という手軽さと、外部電源ジャックも備わっているので電源選択の自由があるのもいい。基板やピン配置の互換性・情報の多さで、「トラブルが起きても調べやすい」のも安心材料。使い心地は非常に良く、電子工作を始めたい人やDIYで何か作りたい人にとってピッタリな一枚板。
Review: A genuine product - It works smoothly. I bought a cheaper version from Temu but its voltage to pins were low causing all the problems and making me troubleshoot for a long hours. I am new to microcontrollers and Arduino and I am going to stick with genuine products from now on.

## Questions & Answers

**Q: Is this an original Italy made Arduino?? or china product??**
A: If it is Arduino, it will say Arduino on the board.  The china board is called Elegoo, at least the most popular one, and it says Elegoo on it.  Pretty straight forward.  I have this board with the exact same packaging as is in the picture and it says Made in Italy.  It also says Arduino on it.

**Q: Do these come with the arduino.org label and not arduio.cc?  There was a falling out and to support original founders they need to be arduino.cc.**
A: New York, NY, Oct. 01, 2016 (GLOBE NEWSWIRE) -- Arduino, the world’s leading open-source ecosystem for Educators, Makers and IoT developers of all ages, today announced that Arduino LLC (aka Arduino.cc) and Arduino srl (aka Arduino.org) have signed a settlement agreement, and Arduino will become one. Please visit Arduino at this year’s MFNY to talk to the team and see demonstrations of Arduino products and more.By the end of 2016, the newly created “Arduino Holding” will become the single point of contact for the wholesale distribution of all current and future products, and will continue to bring tremendous innovations to the market.

**Q: Are the boards sold by Mp3Car Store genuine? Order is fulfilled by Amazon but some sellers are selling fake boards.**
A: The board I ordered from Amazon and fulfilled buy Dfunlife is a complete FAKE!! My first hint that it might be a counterfeit is the board, made in Italy, was shipped from China. I went to the Arduino web site (which I should have done before I ordered this from Amazon) and did a search on "counterfeit Arduino". It came back with a page of excellent instructions on telling counterfeits. Sure enough, there was my counterfeit. The kicker was the 501k component; it was green on my fake board. The Arduino site has a list of reputable distributers. Arduino uses some of the money from the sell of the REAL Arduino boards to support good causes. Counterfeiters just sell junk that tarnishes the reputation of good companies.

**Q: Does it come with a usb cable?**
A: The USB cable is not included
