3.5" LCD touchscreens: Now Available for $10 each.

My supplier for the 4.3" "used" touchscreens has about 1000 new 3.5" units that were never used...
Could be a nice chance to save them from the landfill...
Took a quick look at the datasheet and they appear very similar to the 4.3" units, but have an additional SPI interface.· Not to happy about needing extra pins, but perhaps this interface allows additional functionality...
Update:· Now for sale!· $10 each (+$5 shipping within USA)·
Email ray@rayslogic.com with your order...

Two important things:
- Do these LCD come with processor / memory integrated?
- The price. Less than $5?
I'm just so amazed how you find these items at GOOD prices. I think your doing a great service to the prop community.

Can you post the datasheet?
Depending on the price, I am interested in a significant quantity of these displays.

You need to supply +18 and -10V for the gate voltage as well as +5V for analog logic.
Also, you have to supply 6 capacitors.
So, it's more difficult.· Have to see if the price point makes it worthwhile...

If the LCD has a module, maybe your supplier can give those parties, together with the connector. It would be a great savings.
And the plastic box with the brand erased.
Two (maybe one) MC34063 can provide both potentials.

Unfortunately, it's QFN, not one of my favorites, and with tiny pitch too... [noparse]:([/noparse]
Hopefully, I can find something similar in an nicer easier to solder·package...

Also, got a green light on the datasheet, so here it is:

Hopefully, we can figure out what they all do... I'm hoping they will let you do things like change scan direction so you can rotate the display more easily...

The controller IC seems to be a S6F2002, but I don't find a datasheet.
All in all this display is much more complicated than the 4.3".

Will work for Propeller parts!
Again, these are very interesting because there are ~1000 brand new ones available for a very low cost...
If anyone wants to help develop a breakout board, let me know...

Was looking at TI power chips again yesterday...·The QFN16 ones that look like the best fit.
Probably should check out what other companies are selling too...

They do indeed look brand new.
It does appear that the same 60-pin connector I've been using for the 4.3" units will work with these too...
(rather convenient).
The FPC cable is a bit on the long side, compared to the 4.3" units.· It's also much thinner and without ground plane.
I think that's because it doesn't have any components on the FPC cable...

Haven't made a breakout for them yet, so I don't have any way to test them.
But, they are brand new, so that's not so important...
Hope to have a prototype breakout board in the near future...

Is there any documentation on the 3.5" LCD yet?

Any requests on connector?
I was thinking a 40 pin dip connector designed to fit under the prop dip chip. Would be 6 bit color only.

Looks like the STK1000 uses a very similar, if not identical 3.5" LCD.
And, they've posted complete schematics for how to power it here:

I think I realize what that "M" output is for now...
This should jump start board development!
