Most of the IoT applications use this module for the room status board.The TFT LCD is common in industrial application to show the data in graphic formats, etc.The resistive touch is also available in the LCD.

The SD card option allows storing a large amount of graphical data.The LCD uses a driver and shield for Arduino UNO support, which makes it easy to use.There two communication methods for microcontrollers with LCD, which are SPI and 8-bit data.TFT LCD is operatable with both 5 and 3.3V power input.The single TFT LCD can view the whole image in colors with 240×320 pixels max.The SS pin will enable the SPI communication through the signal of the SS pin. The DI pin is the data input pin of the SPI communication system. The SCK pin the common clock pin of the LCD with microcontroller/ArduinoĭO pin the data output pin of the SPI communication system. The Arduino library mostly uses the SPI pins. It requires only when a developer needs to work with LCD using 8-bit data or using Assemble language. These all pins from D0~D7 are the digital data input pins. The RD pin is to enable the reading of data from the LCD. The WR pin which only requires to activate when the device needs to write the data on the LCD. The RS pin will help to toggle the data/command registers in the driver. The CD pin helps to enable the data from registers to the LCD. The LCD has a reset pin which helps to clear the GRAM of the driver The input voltage will be pass to the LCD by the 5V pin. The ground pins are here for a simple common ground
