ebay knockoff arduino vs genuine 2560 r2

Hi all,
Does anyone out there who has the various arduinos mega brands
know if mounting holes are consistent?
I've a couple of megas from ebay that are obviously not genuine, $25au!, but
I'm stuffed if I can get them mounted into a linksprite case in anything
resembling a satisfactory fashion.
So I was just wondering if the mounting holes do differ.
Or is it that Linksprite cases aren't a good case?

Many thanks,
Andrew
Ps, apologies if this isn't in the right forum. It seemed like the best fit.

All the Arduino boards from China on Ebay are clones. They are 13 dollars.
Since they are clones, they can be anything and therefor I can't answer your question.

In most cases the public information from the Arduino site is used to make those boards, so they should be the same, but with cheaper components.

Looks like there are differences from the "original" mega.

Thanks everyone for the response.
I did realise the minor mistake of using R2 instead of R3.
The boards I have do seem remarkably identical apart from
the underside silk screening to the pictures james c4s linked.
I would have to buy an original board and do a side by side.

Maybe, I'm going to have to Dremel out all the other mounting points
so it might fit the board better. Doesn't matter if it doesn't
work. Broke the top half of the case, drat.

One last question. The clones on ebay, are they legal? Apart
from the aspect of physically identical boards with near
identical/deceptive silk screening?

Many thanks,
Andrew.

Yes, they are legal. The board is open source, public domain. So anyone can make and sell them.
The name "Arduino" is not.

No that is wrong.

If they are called an Arduino then they are not legal. Yes they are open source but you can not call a copy you make from open source an Arduino because that is a trade name. Also all the logos on the board are also copyright.
These are rpip off boards pretending to be something they are not. It is known as “passing off”. Also the conformity marks like FCC logo are used illegally.

They could be confiscated at the customs of your country although I have only heard of this happening on one occasion.

But most of all you are depriving the Arduino project of money and this money pays for things like this web site. So if you just buy rip off boards and continue to use this forum then you are being a parasite.

No that is wrong

My bad, I changed the post.

Hi folks,
Thanks for clarification everyone.
I think whilst the price on the knock offs is tempting for the next
couple of boards, it is at least, ahh, impolite to not to get genuine.

Problem now is how do I know the "genuine" boards on ebay
aren't just the same knock offs stuck in printed box, with the
price jacked up $65?

Oh well, that's a problem for another day.

Thanks again all,
Andrew

Don't buy the official ones on Ebay.
Use the Arduino shop http://store.arduino.cc or a local distributor.
There are many local distributors.
