![]() ![]() Could you please link me to the Chinese ones you bought or some reputable sites? I'm just a teenager with a pretty low budget and would love to save some money. Thanks for you response, and I guess a benefit of buying an official one is that you know it will be good. ![]() 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. 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. 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. 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. They never intended to be the only source for their board designs. 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.Īctual 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. On the bottom of the hardware page was this link, it shows all the past and present versions. Just have to select Uno instead of Duemilanove in the Arduino IDE (programming software). Works fine, and my Duemilanove now boots and loads faster. I am using the Duemilanove, and I bought a new ATMega328P chip and burned the Uno bootloader on it. Otherwise the board is the same shape, pins are the same, and the shields are compatible with both. The bootloader is different, smaller in size and allows sketches to upload faster. The second one is a not connected pin, that is reserved for future purposes. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. Some people have had problems with this chip, search the forums to find out more.ġ.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. What about Amazon? It seems to be about $10 cheaper here, it looks pretty real to me: ![]() I have decided to go with the Uno in that case, since I am just starting out. I didn't know there were fake Arduino's, thanks for letting me know. You will be getting the real deal and supporting the inventors, not the copiers. My main advice is buy the Arduino from a reputable dealer, such as Sparkfun or Adafruit. On the Mega you will be learning how to remove surface mounted ICs, reflow soldering, etc. If you are only connecting a few sensor or components up the Uno is a better choice.Īlso, if you connect something wrong and fry the main chip, it is easily replace with the Uno. The Mega has more "horsepower" under the hood, is larger and has many more digital and analog pins. If you want to learn basic electronics, how to let smoke out of components, the Uno is great. Uno, it depends what you are going to use it for. You might have a lot of problems with the fake Arduino, and some people here despise them.Īs for the Mega vs. Second, its a picture of the real Arduino Mega but the "Made in Italy" in the upper left corner is blocked out. * Define the DIO used for the SDA (SS) and RST (reset) pins.First off that board is a Chinese copy not a real Arduino.įirst clue - it's $15. * Include the standard Arduino SPI library */ in the below the total purchase value will incremented when reading the card first time then decremented when reading the same for second time.
