Features: brand new and high quality 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 For 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 IO for mega- is officially 5V, TFT LCD use 3.3V IO. This Cte TFT LCD/SD shield for mega- provides the connection to a TFT LCD module directly without flying wires. The shield fits two type of TFT LCD module's pinout:(1) 40 pin version LCD which is commonly used in previous version of TFT mega- shield for mega- 2560(2) 32 pin version LCD which is commonly used in Stm32 development board(unsoldered) The shield use True 5V to 3.3V level translation IC, therefore, it is for many TFT LCD modules. Specifications: Size:approx 95mm/3.74in The Shield is for mega-2560 and the following LCD: 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) Package Includes: 1 X TFT/SD Shield Expansion Board note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurment.
