Description
Product Overview
The 3.5-inch TFT Touch Display is a vibrant, high-resolution color screen designed to bring graphical user interfaces (GUIs) to your embedded projects. Powered by the ILI9488 driver IC, this display offers a crisp 480×320 pixel resolution (RGB 65K color) . Unlike complex parallel displays that consume many I/O pins, this model communicates via a simple 4-wire SPI interface, requiring as few as 4-5 I/O pins to operate .
This module comes with a resistive touchscreen (using the XPT2046 controller) and includes a stylus pen for precise interaction . An onboard MicroSD card slot is also provided, allowing you to load images, fonts, and data directly from a memory card . The module features a 14-pin 2.54mm pitch header, making it compatible with breadboards and standard female-to-female jumper wires .
Whether you are building an industrial HMI control panel, a smart home touch interface, a portable gaming console, or a data logger, this 3.5-inch display offers the perfect balance of performance and ease of use.
