3.5 Inch Resistive Touch Display for Raspberry Pi with 480 x 320 Resolution and SPI Interface
The 3.5 Inch Resistive Touch Display (A) for Raspberry Pi is a compact TFT LCD designed to add a responsive graphical interface to Raspberry Pi projects. Featuring a 3.5-inch display with a resolution of 480 x 320 pixels, it provides clear visuals for embedded applications, human-machine interfaces (HMI), portable devices, and educational projects. The integrated resistive touch panel enables accurate touch input using a finger, stylus, or gloved hand, making it suitable for industrial and field applications.
The display communicates through the SPI interface, allowing straightforward integration with Raspberry Pi boards while occupying minimal GPIO resources. Its compact design and reliable touch functionality make it ideal for DIY electronics, automation systems, IoT projects, instrumentation, and portable control panels where a small yet functional display is required.
