I know that Arduino uno and Elegoo uno use chips from the same manufacturarers, but still I was wondering if there's any difference between them in terms of software or similar. In school a professor wants to start making projects with Arduinos and Raspberry pis and etc. So one project we saw online online requires an Arduino uno (the most basic one), but we saw that an Elegoo uno is way cheaper, so we were wondering if the same code could work on both. Sorry if it's a dumb question, we're basicly newbies.

  • At ebay/aliexpress you can get an Arduino (compatible) R3 for about $3 – Michel Keijzers Jun 26 '17 at 16:17
  • This is unanswerable, because it refers to a brand not a specific product. To ask about a specific product in comparison to an Arduino, you'd need to include its specifications in the question. Generally speaking the biggest issue, apart from mechanical fit & finish (or trademark infringement by those who, unlike they one you seem to be talking about, don't put their own name on the product) is various cheaper USB/serial solutions which may have driver or electrical robustness issues. – Chris Stratton Jun 26 '17 at 17:54
  • @ChrisStratton The question is tagged with "Arduino-Uno", but apart from that it is indeed hard to say if the Elegoo is "as good as" an official Arduino. – Paul Jun 26 '17 at 18:11
  • The raspberry-pi package actually doesn't include the raspberry pi itself – Paul Jun 26 '17 at 18:20
  • @Paul Elegoo has more than one model of Arduino-like board. – Chris Stratton Jun 26 '17 at 18:30

You should:

  • Contact Elegoo and ask them if there is any support/return possible.
  • Consider buying an official Arduino, to support Arduino.
  • Consider even cheaper options.

Software wise, any "Arduino compatible" board will work with the Arduino IDE, if not, you should return it (if possible).

Some boards may have cheaper hardware and cause issues with:

  • Serial drivers (some use a cheaper chip, but this often can be fixed)
  • Input voltage or power stability
  • Durability (including min/max temperature)

So you should consider if support or the possibility to return a product is more important than paying a little more.

    And don't forget the temperature range of the crystals and capacitors. The cheapest crystals stop working below 0°C, the genuine Arduino boards don't stop. The ATmega328P microcontroller has a temperature sensor inside. Therefor, when cheap clones are put in a freezer to test the temperature sensor, the clone might completely stop working. – Jot Jun 26 '17 at 19:22
  • That's true, however it's hard for me tot say, an "elegoo" could even be more durable. Nor that you would be very likely to use one below 0°C (isn't a very typical setup) but I appreciate your addition and concerns – Paul Jun 29 '17 at 21:20
