you sell the Color LCD TFT 3.5" 320x240 SKU#: LCD-08490, but no connector for it, that seems a bit strange for SFE. usually you dont leave us hanging like that. i suggest you add a connector for it as well.
or at the very least, give us a part# where to get one.

i can’t speak for SFE, but we use the same connector in a new product. the lead time for this connectors is about 16-24 weeks, so i suspect that SFE has some on order, they just haven’t arrived yet.
this part should work:
kyocera/elco/avx 04-6240-054-005-800+
if you check with both mouser and digikey, they show they can get it, but don’t provide lead times.
I am surprised SFE left us hanging on this one, hopefully they will learn if they cannot provide the mating connectors for something they probably should not sell it.
Anyhosel, i just got these molex connectors in and it looks like its a winner. I am making a board for it and will let ya know for sure and how well the screen looks.
Molex part# 0512965494

looks like mouser has some of the elco connectors in stock right now:

i’ve ordered some of the Molex part to test as well.
I don’t know about you, but after looking at the SFE data sheets on this LCD, i cannot figure out how to wire up many of the pins and what they do.
I hope SFE will post more info on it.

we have a couple commercial projects using similar displays(hence my interest in the connectors). feel free to ask in this thread about any connections.
Thanks,
the following pins i am not 100% sure of.
#1) i am assuming pins 39,40 (AVDD) connect to 41,42(DVDD)
#2) 44,45 (VGL) ???
#3) 47 (VGH) ???
#4) 50,51 (VCOM) ???
#5) 36,37,38 (HSYNC,VSYNC,DCLOCK), I know i wont be using these but what is the termination (high, low, float)?
#6) most importatly, since there are no mode pins being brought out to header, i dont know if its in serial or parallel mode.
#7) when you go to the chip driver data sheet there are many more pins it mentions which again are not brought out on the connector. so what are the state of these pins.
#1) i am assuming pins 39,40 (AVDD) connect to 41,42(DVDD)
normally the DVDD is 3.3v and the AVDD is 5V
VGL is the Video Logic Low reference voltage, usually -10V#2) 44,45 (VGL) ???
#3) 47 (VGH) ???
VGH is the Video Logic High reference voltage, usually +18v
#4) 50,51 (VCOM) ???
vcom is the line driver input, its usually tied to the polarity input (marked as M)
#5) 36,37,38 (HSYNC,VSYNC,DCLOCK), I know i wont be using these but what is the termination (high, low, float)?
why won;t you be using these? wil you but running in spi mode?
#6) most importatly, since there are no mode pins being brought out to header, i dont know if its in serial or parallel mode.
by default when the lcd powers on it defaults to the parallel input mode. to switch to serial mode you will need to configure via the spi interface.
#7) when you go to the chip driver data sheet there are many more pins it mentions which again are not brought out on the connector. so what are the state of these pins.
generally if the pins aren’t used they aren’t brought out and are usually terminated per the datasheet.
Thank you so much for taking the time to explain things.

Oh boy!, you turned on the light for me, and i see that i am a total MORON :roll:
I don’t know how, or when i got the idea that it had a built in controller.
i guess my excitement for it surpassed my desire to check the data sheets out more throughly.
Oh well…

where did you order them from?
i got the samples at molex.

Does anybody see where this is in the datasheet? None of the registers I see have anything to do with the input mode.
