Richer-R Expansion Board,for Arduino MEGA 2560 LCD Module 2.8/3.2inch TFT Memory Card Shield Expansion Board,Shielding Adopts True 5V to 3.3V Level Conversion IC
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•The for Arduino MEGA IO is officially 5V, while the TFT LCD adopts 3.3V IO. This CTE TFT LCD memory card shield for Arduino MEGA connects directly to the TFT LCD module without flying wires.
•The shielding adopts TRUE 5V to 3.3V level conversion IC, which is therefore compatible with many TFT LCD modules.
•The compatibility is wider than the conventional TFT Shield, which converts 5V to 3.3V using resistors or buffers. Using this method to convert the IO level to 3.3V May cause compatibility problems, especially at high write speeds.
•The shielding is suitable for two pin arrangement of TFT LCD modules: (1) 40-pin LCD, often used to block TFT from previous versions of for Arduino MEGA 2560; (2) 32-pin LCD, commonly used for STM32 development board (not welded).
•The for Arduino MEGA 3.3V is 150mA, and the output may not be enough to drive a larger screen (e.g. 7inch, 5inch LCD module). Therefore, the shield board has a voltage regulator of 1A 3.3v , which can provide sufficient current
