Description
Product Overview
The 2.4-inch TFT LCD Touch Screen Shield is a plug-and-play display module designed to add colorful graphics and touch interaction to your Arduino projects. This shield fits directly onto Arduino Uno, Mega 2560, and compatible boards, creating a complete human-machine interface without any soldering or complex wiring .
With a resolution of 240×320 pixels and support for 18-bit color (262,000 shades) , this display brings vibrant graphical user interfaces to embedded projects. Whether you are building a weather station, a control panel, an oscilloscope, or a retro gaming device, this shield provides the visual feedback and touch input needed for professional-looking projects .
The shield is compatible with two common driver ICs—ILI9341 and ILI9325—and uses the XPT2046 resistive touch controller. An onboard MicroSD card slot allows you to load images, fonts, and data from a standard memory card, extending the display’s capabilities for data logging and photo viewing applications .
