"Wireless" Arduino Mega 2560 board ?

[WaveyDipole]

I'm not sure if I can put a link to the auction on here, but I have seen several of these for sale on eBay described as "Wireless 2560 R3 Mega2560 REV3 ATmega2560-16AU" Board For Arduino Module". Now, there slightly more expensive boards with an ESP8266 chip included on the board which are clearly identified with ESP8266 in the title and the dark PCB, so clearly these do have WiFi. However, there are other boards described as "wireless" Mega 2560 boards of the "Elegoo" variety that do not seem to have an ESP8266 or other WiFi controller on board, just a 16u2. Having checked the datasheet, I the 16u2 does not seem to be  capable of providing wireless functionality (neither WiFi or BlueTooth), so how is it that these boards are described as "wireless"?

Probably just copy/pasted from other auctions of similar boards that actually had wireless capability (be it 433M/868M/2.4G etc..).  Often large ebay shops that sell these things have no idea what they actually are, so they just buy up stock, copy the details from other auctions and put em up.  I have no idea what Elegoo is, probably just an Arduino clone?

wireless --> no USB cable included

Ding, ding, ding! oPossum wins. This is the same error as the "wireless" grounding straps. It literally means it doesn't include the wire/cable.

wireless --> no USB cable included

Thanks for pointing that out! Now that you have mentioned it, and having looking again, it seems that although one of the images features a cable plugged into the USB port, there is indeed no mention in the listing detail that such a cable is actually included. There are also some slightly different listings that actually show a separate USB cable and most of such listings do state that one is included (sometimes described as  a "free USB cable") although naturally the selling price is usually higher.

Anyone who thought they were getting a cheaper WiFi capable board will be disappointed!

Caveat emptor.

Yes, caveat emptor whenever reading materials written in a language that is not native to the country/company/person writing it.

Common electronics gotchas on eBay, AliExpress, etc.:

What they write	What it (usually) is
Wireless	Wire/cable not included
4-bit display	4-digit display
Nixie display	LED or vacuum fluorescent display
Digital tube	LED
