3.5" 480×320 IPS Capacitive Touch Screen

SKU: DFR1092

This 3.5-inch capacitive touch screen, with a resolution of 480 × 320, is designed for display projects and features high-quality IPS technology and optical bonding for a wide 178° viewing angle, clear display, and reduced glare. It supports 5-point sensitive touch, offers two flexible hardware connection methods (SPI and GDI), and includes a Micro SD card slot. The screen is suitable for IoT control panels, desktop weather information screens, portable game consoles, and various touch interaction interfaces, and is compatible with the Arduino GDL library, providing rich examples to accelerate development.
