Dear all,

sorry for what might look like a silly question, but I could use a little help to understand what is the difference between:
Arduino certified, arduino clones, derivatives, and counterfeit.

thanks in advance for your time and apologies if this post does not fully match what is expected in this topic...

Certified: Manufactured for and sold through the Arduino organisation.

Clones: Use most or all of the Arduino schematics and board patterns but branded differently.  Quite legitimate as long as they are not claimed to be an original Arduino.

Derivatives: Enhancements or at least variations to the circuit, distinctly branded.  Quite legitimate as long as they are not claimed to be an original Arduino.

Counterfeit:  Use most or all of the Arduino schematics and board patterns but branded to imitate the genuine product.

Also you should be aware that some of the arduino clones, derivatives, and counterfeit replicas might be using fake atmega IC's that works similar to the original ones but they are not original and sometimes they have problems with simple calculations that screw all your project making it non-workable.
But for easy things, they do the job :) and also with more complex things they do the job (or not) it depends on their mood :P

Can you point to an actual example of that?
Really bad counterfeits probably won't work at all, or have a different chip than advertised (lately there have been several instances of people ordering Atmega328-based boards, and getting a board with an ATmega8.)  And there are boards with counterfeit USB chips (prolific being widely counterfeited, in particular) that may have issues with USB drivers.  But I've never heard of a "partially functional" counterfeit giving bad results to calculations...
