My latest CP2102 based device from eBay has arrived, and whilst the image looked like the one in this article it was of a slightly different design which means this mod cannot be effected.

So if you are buying one it might be worth checking with the seller that it is exactly as illustrated.

How about some more info?

like a link to the ebay auction you DID purchase from?  (and ebay seller name)

and also maybe a pic of the hardware/device you DID get?

if I was bait-n-switched... I would have gotten a refund.

Well, this is what I thought I'd bought..

http://www.ebay.co.uk/itm/110760144325?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

But this is what arrived (taken at random, just to illustrate)

But it does "what it says on the tin", so no grounds to return it. Plus it would probably cost more in carriage costs than it cost to start with.

Yep, you got screwed.

This happened to me one time.  I simply wrote the seller with a picture of what I received, and pointed out that the picture differed from what was advertised.  The seller posted a replacement of the right type.

eBay sellers usually dislike negative feedback.  If what they sent does not match what was advertised then that is cause for negative feedback.

On the other hand if you ordered the wrong one because you did not inspect the photos, or there where no photos to inspect, then the fault is yours.  On the bright side, you should not have spent more that a morning cup of coffee on the board.

I know that most people complain about the quality of parts from China, and they are right.  However, for the savings, I am usually willing to put up with the lower quality to save some money.  I do this as a hobby, I enjoy playing with these things.  If I where making a production quality product, with my name on it, I would source my part with greater care.  But I'm not, and I don't.
