Hi,
I have for sale a shield board based on a HY28A-LCDB, SPI driven with Touch Panel. This is the (now) third version of this popular add-on board.
This version is now supplied with a 26-way connector, so you don't need to solder directing onto the PCB for for additional hardware.
You also now have the option to connect it to the Pi via a ribbon cable. Here it is connected to my Rev1 Model B Pi :

Custom case is also available (only compatible with Revision 2 Pi's) :

Features include
320 x 240 resolution @ 20fps, 65536 colours.

The board draws approximately 64mA from the 3v3 line, supplied by the Pi.
Screen and TP use hardware SPI ( SLCK, MOSI, MISO, CE0 & CE1 ) plus 3 additional GPIO lines ( GPIO17, GPIO18 & GPIO25 ), keeping the other GPIO lines free for other uses via the 26-way _GPIO connector.

Setup and configuration details : viewtopic.php?f=64&t=48967

Ready assembled and tested unit will cost £25 plus postage.
The case is available for £12
10cm ribbon cable is available for £3

Postage costs for single items are :
UK - £4
Europe - £5
Rest of the World - £5
but note that multiple items may cost more to post.

Nice addition!
Very handy for the others things you might want connected as well as the TFT.
And being able to use on a ribbon cable... NICE!
I'm not much of a crafting type but that will make adding to other cases so much easier!

Hmmm...do I need another one...

Hello Texy,
very nice addition!
Please: can you send info about how to send you money? :-)
I'm in trouble with "private messages"... :-(

TIA

Hi Texy !
This is a nice change to your board ;)
Soldering an angled connector to the assembled kit was not really easy on the first version, and it reverts the wiring. Does your new board allow using a pi-cobbler, without inverting the wiring ?

You can see your board + screen in action on this thread...

Hi,
great job!! I would really like to see a tutorial on getting Frontier running on the Pi - I,m sure many others would too.

Regarding the new v1b shield board - there are 2 options for connecting it to the Pi. One of them is direct connection to the Pi GPIO port - on the shield board this is a female header. The other is via a ribbon cable, this is a 'mirrored' connection using a male header. This connection, which I labeled as "_GPIO" on both versions of the board, is different on the 1vb board, as the v1a board was not 'mirrored'. Hopefully that is clear :?

I can't send you a PM. Posting a reply here per your instructions re adding a ribbon cable to my shipment.

Hi, i'm new on this forum.
I'm really interested and i'd like to buy a 2.8" TFT + Touch shield but auction on ebay ended this morning.
You will renew the auction or can i buy it sending you every info via PM?

Thanks

On the right (assuming you have the standard skin in the forum) you'll find a button marked PM under his name. Click that and add your message there. No need for an auction of some sorts, he has them in stock :) (I have 2 from the earlier batch, but now consider a 7" TFT, along with some more RPi's ;) )

Having the possibility to use a ribbon cable to plug the screen to the Pi is a very nice addition.
It's my own opinion, but I think I prefer the v1a design, with the GPIO extender on the top. I think the R-Pi has more room for cooling (this thing tends to get hot ^^) and plugging/unplugging without removing the entire display is very handy (in my case). Assuming the display is plugged directly on the GPIO, without the ribbon cable, of course... I could post a picture how I did it, to make it more clear.
Edit : a few pictures to show how I made it on the v1a board. I had to use a female connector with long pins, and cut/bend/solder each pin separately. Not a easy thing, but I'm really happy with it now.

Pic 3

As requested, the 'tutorial' to make Frontier 'run' on the Pi is available here. It runs very nice on HDMI, now I'm investigating to make the same on this nice 2.8 TFT :)
If anyone knows how to make a software run on the TFT from the command line, without my dirty hack relying on xinit, I'm very interested ;)

In the same post, I indicate how to fix the DPI in X. It may be useful for this topic.

Hmmm. This looks quite amazing. Could the whole thing be attached to a:

Making the whole mess portable?

Hi, i'm also new on this forum.
I can`t write a PM. I would also like to order a 2.8" TFT + Touch Shield Board v1b. What can I do?

Thanks

Just to make sure: With a v1b board, are the GPIO pins assigned in the male header like in this picture:

Hi,

I see that there's no LCD listed on ebay anymore, only the case. Have you stopped producing the LCDs, or it's just a temporary shortage? I'm interested in buying one.

Thx

Basically I am on holiday from tomorrow for a week so i let the eBay items finish and I was going to relist when I get back.
I have plenty of stock. I will take pm orders but I need payment before tomorrow otherwise they will not be shipped for a week.

Thanks for the answer.
I'll wait for the eBay items to be relisted, there's no such a hurry.
Have a nice holiday!

@texy: thank you for your contribution, providing a great base for a while lot of new applications with a great form-factor for the PI.

As it happens, I have a couple of these: http://www.ebay.co.uk/itm/181008290930 pending to arrive in the next days and, as they look pretty similar to your LCD and also have the ILI9320 controller on board, would like to know if you could tell:
- if these are known to you
- if they are compatible to your adapter board and the driver configuration mentioned in this topic (does your adapter board have 2mm pitch connectors?)
- what is the best way to purchase only the adapter board in this case, as there is no ebay listing for the adapter board alone (I'll have to wait for account approval to be able to PM you)

Thanks again!
