First off that board is a Chinese copy not a real Arduino.First clue - it's $15. Second, its a picture of the real Arduino Mega but the "Made in Italy" in the upper left corner is blocked out.You might have a lot of problems with the fake Arduino, and some people here despise them.As for the Mega vs. Uno, it depends what you are going to use it for.If you want to learn basic electronics, how to let smoke out of components, the Uno is great.The Mega has more "horsepower" under the hood, is larger and has many more digital and analog pins.If you are only connecting a few sensor or components up the Uno is a better choice.Also, if you connect something wrong and fry the main chip, it is easily replace with the Uno.On the Mega you will be learning how to remove surface mounted ICs, reflow soldering, etc.My main advice is buy the Arduino from a reputable dealer, such as Sparkfun or Adafruit.You will be getting the real deal and supporting the inventors, not the copiers.

QuoteYou might have a lot of problems with the fake Arduino, and some people here despise them.I've got a 328 arduino and a mega, both made in china, and both work as expected. What makes you think electronics made in italy are better than electronics made in china? Of all the electronics you own, how many are made italy? How many are made in china? ever own an italian car? I've had good service from the below vendor.http://www.ebay.com/itm/1-Funduino-Mega-2560-ATmega2560-16AU-Board-Arduino-compatible-Free-USB-Cable-/251143019741?pt=LH_DefaultDomain_0&hash=item3a794a5cdd
Are fake Arduino's really as bad as everyone say they are?
JD3 as well as some other people with a bit of research.http://arduino.cc/forum/index.php?topic=1535.0If you look at my previous post that is edited I noticed two different voltages. I believe that will make a difference considering how I will need to use different resistors?I mean, I can save a significant amount of money (66%) by buying a Chinese version but I'm not sure if it's worth it (any problems with Chinese knockoffs?).
Wow, pretty good price. Are fake Arduino's really as bad as everyone say they are? I mean I'd love to support the creators though, they worked hard on it.
QuoteWow, pretty good price. Are fake Arduino's really as bad as everyone say they are? I mean I'd love to support the creators though, they worked hard on it.Actual the term 'fake' is a misnomer as the arduino folks have released all the hardware design files to be open sourced from their very beginning. They never intended to be the only source for their board designs. What the arduino folks have tried to get others to respect and obey is their trademark of the Arduino name and the various branding artwork and that is why there are so many funny named boards ending with a -uino suffix. The quality of Asian 'arduino compatible' boards may vary from firm to firm but of the couple I've bought they were first class and have stood up as well as the 'real' arduino boards I have. Some of the Chinese firms do try and stay away from branding and naming violation, but most are pretty blatant and try and make it near impossible to tell that it's not a 'real' arduino board. So buy what you want for the reasons you want, but don't believe all the hate and anger some try and hoist on every Chinese seller of arduino compatible boards, as some are playing by the rules and there is not a quality question on most of them in my opinion.Lefty
Could you please link me to the Chinese ones you bought or some reputable sites?
QuoteCould you please link me to the Chinese ones you bought or some reputable sites?Sorry, I just normally shop for such stuff on E-bay and tend to buy on impulse so I have little memory on what firm I purchased what from. Just read the listings, look at the sellers feedback count and percentage positive. Most Asian sellers I've dealt with on E-bay are very protective of their feedback ratings and will normally work well with you on any issues, I've had only a couple of issues in maybe a hundred purchases and both were just having the wrong thing shipped which was corrected. The biggest issue many have with the Asian sellers is the rather longer shipping time then in country sellers can do. Here on the west coast I usually get my stuff in 10-11 days which is fine by me. As I'm retired the fasted clock I go by is a seasonable one. Typical search for Uno R3 on E-bayhttp://www.ebay.com/sch/i.html?LH_BIN=1&_sacat=0&_from=R40&_nkw=arduino+Uno+R3&_sop=10
Yeah, shipping from China takes ages. Thanks for all your help but one last question - as you can see, the bottom left of most Chinese made Arduino boards says 25V, although the official one says 16V. Will this be a problem at all?
