TFT/SD Shield for Arduino MEGA 2560 LCD Module SD level translation 2.8 3.2 DUE
Description:
The IO of arduino MEGA is officially 5V, TFT LCD use 3.3V IO. This CTE TFT LCD/SD shield for arduino MEGA provides the connection to a TFT LCD Module directly without flying wires.
The shield use TRUE 5v to 3.3V level translation IC, therefore, it is compatible with many TFT LCD modules. Compatibility is highest when compared to ordinary TFT Shield, which use resistors or buffer to "shift" 5V to 3.3V. Compatibility issues may arise when using this method to translate IO level to 3.3V, especially at high write speed.
The Shield fits two type of TFT LCD module's pinout:
1. 40pin version LCD which is commonly used in previous version of TFT Mega shield for Arduino MEGA 2560
2. 32pin version LCD which is commonly used in STM32 development board. (unsoldered)
Check the pinout HERE
Arduino MEGA 3.3v is 150mA, the output may not be enough for driving larger screen (e.g. 7", 5" LCD modules). Therefore, this shield has a onboard 1A 3.3V regulator to supply enough current to the screen.
The shield is compatible with Arduino MEGA 2560 and the following LCD , which is avaliable in our store:
2.2" TFT LCD Module (220x176)
2.8" TFT LCD Module (320x240)
3.2" TFT LCD Module with Font IC (320x240)
3.2" High Resolution TFT LCD Module with Font IC (480x320)
3.5" TFT LCD Module with Font IC (480x320) (Full viewing angle IPS panel)
4.0" TFT LCD Module with Font IC (480x320)
4.3" TFT LCD Module with Font IC (480x272)
5.0" TFT LCD Module with Font IC (800x480)
7.0" TFT LCD Module with Font IC (800x480)
The shield support Henning Karlsen's UTFT library, which can be downloaded here:
http://electronics.henningkarlsen.com/
Together with these SPIFlash, the shield also support Henning Karlsen's SPIFlash library, which can be downloaded here:
http://henningkarlsen.com/electronics/library.php?id=66
To use it on the UTFT library simply:
2.Change the LCD type to your LCD module eg. UTFT myGLCD(CTE50,38,39,40,41);

If you using Arduino DUE, the shield is HERE
Packing list:
1. CTE TFT/SD Shield for Arduino MEGA 2560
2. 32pin header
Features:
- True 5V to 3.3V level translation using TI SN74ALVC164245 for LCD data lines, TI SN74LVC4245 for LCD control line and SPI lines
-
Highest compatibility. One shield for many types of TFT LCD modules.
- Drive TFT LCD on arduino DUE by just plugging into arduino MEGA 2560 main board, no flying wires.
- Compatible with 40-pin version LCD, which is commonly used in TFT Mega shield
-
Also comptabile with 32-pin version LCD, which is commonly used in STM32 development board
- On board SD card slot
- On board SPI flash footprint with adjustable CS selection, for upgrade to include Font IC to draw text to the LCD and also support for SPIFlash library
-
On board 1A 3.3V regulator for provide enough current for larger screens
- LCD power 3.3V and 5V selectable through solder jumpers
- LCD Backlight (LEDA+) 3.3V., 5V or PWM selectable through solder jumpers
