[Pro2 PLUS] warning about some 2.8 SPI TFT (ILI9341) displays on eBay.
#1
Recently some eBay sellers started sell what appear to be a new version that isn't a replacement of our well know ILI9341 2.8 SPI TFT display.
What makes things worse is that, a large number of sellers are selling these new version without knowing that it is quite diferent (they are only sellers, not tecnicians), and don't even have changed the pictures in their listing. If you could see both versions, side by side you will see they are quite diferrent.

What seems to be the latest version, is not compatible with WeatherDuino. The display will work fine, but the touch panel will not work.

So, if you have received from an eBay seller one of those new hardware versions, and the seller isn't upgraded the listing pictures to reflect a correct picture of the new item, you can reclain for a refund, based in the "item is not as pictured".


To illustrate this, here are some very poor quality pictures

   
Back Side

On the left, new PCB new circuit.
On the right, our well know ILI9341 2.8 SPI TFT display

   
Front Side

On the left, the new PCB. Please note that connection of the touch panel is at a completely different position. Readings will also be different in range and value.
On the right, our well know ILI9341 2.8 SPI TFT display.

Vendor says its an ILI9341, for me its an SSD1289. Does it work is SPI mode? Too many pins, it seems parallel mode.

Any user which receives one of those "new" versions from an eBay seller should immediately check it the picture on the product list is diferent of the received product, if yes, contact immediately the seller requesting a return based on the fact that the received product doesn't match the pictured product.
Don't accept any excuse from the vender and go up to escalate the case to eBay resolution center.

I had a recent issue with these "new" displays, and at the end the seller opted by a full refund instead of pay for the return of the product. eBay imposed that the seller should pay for the return, as I proved that the received product isn't as pictured.

The only difference is the type of touch panel (less sensitive and lower resolution). It is also rotated in relation to original.
Yes, it is somewhat hard to adapt the existing code to work with it.

OK, thanks for explanation of differences Werk_AG
My touchscreen arrived already in December, so I'll leave it in drawer and will use it in another project.
I've already ordered another one, hopefully correct type will arive... otherwise I'll have second useless but now maybe for free after refund :-D

it's really hard to find the old screens, I found a model still different from others.

The statement of that seller isn't true. Contrary to what the seller say, you can't use the new ones in a project designed for the older models. As said in previous posts, the screen will work, but the touch panel not.

Unfortunately most of the sellers not even know what they are selling.

Out of curiosity, when it arrives please report which chip is installed on the backside of the board. XPT2046 or HR2046 ?
