TFT 2.4" 320*240 With SD Touch Module (Arduino Compatible)
2.4-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),2.4 inch TFT LCD screen.The LCD has a wide viewing angle , the contrast is also very suitable.
The Screen include a controller ILI9325, it’s a support 8/16bit data interface , easy to drive by many MCU like STM32 ,AVR and 8051.
It is designed with a touch controller in it . The touch IC is ADS7843 , 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.
Module size 75 * 53mm.
There are two 3mm mounting holes and interface is spacing 2.54mm 2*20 pins.
Interface Definition :
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 default use the 8bit mode , and if you need the 16 bit mode, you can tear the LCD screen down form the board , and move the R2 resistor to R1 to change the data mode. It’s a hard job , and easy to destroy the screen, so if you need a 16bit mode , you had better tell us before shipping , we will set the data mode for you. When you use the 8bit mode , the DB8-DB15 is used ,please remember to pull the DB0-DB7 to GND.
Reference circuit : Because the file is a little large, if you need ,please contact with us.
