Overview
ITDB02-2.4S module is 2.4" SPI TFT LCD with 262K color 320 x 240 resolutions. The controller chip of this LCD module is ILI9341V. Since its interface is SPI, you need 6 Dupont lines (SCK,MISO,MOSI,CS,D/C,RST) to control the LCD module. Moreover, there is an on-board micro SD card slot for multimedia storage and data logging purposes. This 2.4" LCD is a resistive touchscreen as well, so you can detect finger presses anywhere on the screen.
Features
- Compatible for 3.3/5V operating level
- Integrated with an micro SD card slot
- Support IO/PMW to control the backlight
- Resistive touchscreen
