The 3.5 Inch SPI Interface TFT ILI9488 Touch Screen Display Module is the largest and highest-resolution display in the StemVolt TFT range, featuring a 480×320 pixel full RGB color panel driven by the ILI9488 driver IC — 2.25 times more pixels than the 2.8-inch ILI9341 module and over 15 times more pixels than the compact 1.8-inch ST7735 — providing the screen and resolution for detailed graphical user interface panels, image viewers, sensor dashboards, and touchscreen menus that are more readable than smaller TFT modules. The 3.5 inch tft lcd display connects via 4-wire SPI alongside the resistive touch controller and SD card slot, all on a 56×98mm PCB suited for panel-mount and open-frame project.
The tft ili9488 with sd card extension is the only display in the StemVolt range with an onboard SD card slot, allowing the microcontroller to load full-resolution bitmap image files from a FAT-formatted SD card rather than storing image data in the microcontroller’s flash memory or SRAM — making it practical for photographs, splash screens, and multi-image interfaces that exceed available microcontroller memory. The resistive touch layer detects stylus, fingernail, or pen input mapped to the 480×320 pixel resolution.
The ili9488 tft display arduino logic level is 3.3V TTL — when using with a 5V Arduino board, a logic level shifter on all SPI and control lines is required to prevent damage to the 3.3V ILI9488 IC, whereas 3.3V ESP32 boards connect directly without a shifter. This arduino tft touch screen display ILI9488 3.5 inch module is ideal for ESP32 Arduino large color GUI touchscreen image viewer SD card dashboard.
