Description : 40 Pin 3.2″ TFT Touch Screen LCD Module
3.2-inch TFT Color LCD Module is a TFT LCD Screen Module, 40pins interface, not just a LCD break but include the Touch, SD card and Flash design. So it’s a powerful extension module for your project. This item is 240374PQ . It’s a 65K color , 320*240 (resolution), 3.2 inch TFT LCD screen. The LCD has a wide viewing angle, the contrast is also very suitable. The Screen include a controller ILI9325 or SSD1289 or ILI9341, we will ship randomly if you have no any requirement (ILI9341 will be in advance) thanks very much!It’s a support 16bit data interface, easy to drive by many MCU like Arduino、STM32、AVR and 8051.It is designed with a touch controller in it . The touch IC is XPT2046, and touch interface is included in the 40 pins breakout. We will offer two version of it, one is with touch screen and touch controller, another is without the touch function, it will just use as a LCD screen for display- so it will be inexpensive than former. Another useful extension in this item is the SD Card socket. It use the SPI mode to operate the SD card, the SPI interface include in the 40pins breakout .There is a reserve extension design in it, that’s the external flash. It’s leave the pad and the pins out for the SST25VF016B Flash. So when you need, you can easily add a external flash for your project .It layout a 40 pins interface for your project, the interface include LCD bus, SD card bus, Touch screen bus and the Flash bus.
Pin Definition :
The pins named with “D_” is the touch bus, the pins named with “SD_” is SD bus, the pins named with “F_” is Flash bus.It is work at 3.3v DC, if you need to connect the module with the 5v voltage I/O , you need to add the 30k and 20k resistors to reduce voltage.It support that it can default use the 16 bit mode.
