I ordered an Arduino from Arduino.in.th which stopped working very quickly the price was 600 Baht (or about US$20) which seemed like quite a bargain when I was purchasing it. I then decided to buy another Arduino from thaiduino.com for over 1,000 baht and this one seems to be genuine. I was then quite curious about what the similarities and differences are, so I decided to take some photos of the two for side by side comparison. Can you tell which one is the fake?
