I thought I was avoiding all of the clone issue buy buying "original" products from the official Arduino store.
The descriptions on the store should be much clearer, and should link to related products as there are similarly named products.
All in all a very poor first experience with Arduino.
The description specifically refers to "Arduino USB-to-Serial adapter" which sounds like an accessory not another board, how was I to know it wasn't the "USB/Serial Converter" accessory but the "USB 2 Serial Converter" board. :(
Yes, that "USB 2 Serial Converter" looks like what was intended for that board.
I completely agree that the marketing (organization, illustration, examples, documentation, even the names) of Arduino products, clones and accessories is generally a mess. Part of that is just what we can expect from an open-source marketplace where people are free to do whatever they wish.
But particularly galling are the relatively sophisticated and inexpensive items (boards, etc.) for which there is NO technical documentation whatsoever. They seem to be sold by people who don't know an Arduino from an artichoke. Several of the Asian vendors are the worst offenders in this respect.
