3.5″ SPI TFT Touch Display — ILI9488 Driver
Article by :- Shikhar Dwivedi
INTRODUCTION
ILI9488 driver 3.5-inch SPI TFT Touch Display is a color LCD module for microcontroller-based display applications with high resolution. Its 320×480 pixel resolution, SPI interface, and resistive touch panel provide compromise of visual accuracy, responsiveness, and ease of integration.
This screen is best suited for deployment on mainstream platforms such as Arduino, ESP32, STM32, and Raspberry Pi to enable developers to build rich graphical user interfaces for automation, embedded, and IoT applications. The ILI9488 controller is well geared to drive smooth colors and stable communications via SPI or parallel interfaces.
Small, hungry for power, and easy to develop, this display offers a scenic, professional-grade screen solution to developers who wish to create interactive dashboards, control panels, or monitoring interfaces without any hardware cost.
