Hi all.
I am looking for 1.8/2.0 inch Touch TFT display with micro SD card socket, but most of them used large piece like:
2.4 inch tft sd.JPGquestions:
1. seems the 1.8/2.2 inch lack Touch function? even the picture above is 2.4;
2. with mini SD socket is more rare?
3. possibly to do modify?

Thanks
Adam

The smaller socket will not fit on the Printed Circuit Board.
Its true, guess I need wiring some thing.
BTW. what's the easy use PCB design software current? I used to use Proteus.

also put another size issue for solution:
The rotary encoder as picture below, it is kind of big, how to make it smaller? or where can find smaller one?

Is the SD card actually connected to the display? I have used displays that have a card socket, and they are wired completely separately, or just connected to the lines of the SPI interface. If that is the case, you can put the SD card on the board that outputs the SPI signal.

Yes, guess I got keep that way. actually I am using it this way a long while.
the reason I like try to keep SD on the board of TFT is that my testing before shown that the SD not works well when used separately, especially with Touch TFT.
