2.8 Inch ILI9341 TFT Touch Screen Module with SD Slot

At 320x240 pixels and 262,000 colors, this display has real room for a graphical interface - icons, graphs, multi-line text - rather than the single-line readout a small character LCD manages, and the 4-wire resistive touch panel turns it into an actual input device rather than a display-only screen. That combination is what lets a project build a genuine touchscreen menu system rather than relying on physical buttons for navigation.

An onboard microSD slot sits alongside the display controller, useful for loading bitmap images or logging data without a separate SD module taking up more board space and wiring. Four white LEDs provide backlighting bright enough for normal indoor use, and the 8-bit parallel interface with control lines is well-supported by mature graphics libraries for Arduino Uno and Mega.

Common uses are touchscreen control panels, simple GUI-driven instrument displays, and any project wanting real graphical interaction rather than a plain text readout.
