CTE TFT LCD / SD Card Shield For Arduino MEGA2560 With 5V To 3.3V Level Translation IC

Description:

The IO of Arduino MEGA is 5V, TFT LCD uses 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 uses 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 uses 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.

The shield is compatible with Arduino MEGA2560 and the following LCD:
2.2" TFT LCD Module (220×176)
2.8" TFT LCD Module (320×240)
3.2" TFT LCD Module with Font IC (320×240)
3.2" High Resolution TFT LCD Module with Font IC (480×320)
3.5" TFT LCD Module with Font IC (480×320) (Full viewing angle IPS panel)
4.0" TFT LCD Module with Font IC (480×320)
4.3" TFT LCD Module with Font IC (480×272)
5.0" TFT LCD Module with Font IC (800×480)
7.0" TFT LCD Module with Font IC (800×480)

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.

Feature:

– 5V to 3.3V level translation using TI SN74ALVC164245 for LCD data cable, TI SN74LVC4245 for LCD control cable and SPI cable
– High compatibility. One shield for many types of TFT LCD module
– 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 include Font IC to draw text to the LCD and also support 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
