3.5″ Touch Screen LCD Raspberry Pi Display

Product Description The 3.5 inch Raspberry Pi Touch Screen is a compact, high-quality display designed to plug directly into the GPIO header of any Raspberry Pi model. With a 480x320 resolution, it provides a crisp interface for Raspbian, Kali Linux, or custom Python-based GUIs. This display utilizes a high-speed SPI interface (up to 125MHz) to ensure smooth frame rates, making it ideal for portable projects, mini-consoles, or server monitoring dashboards where a full-sized HDMI monitor is impractical.

Key Features

• Seamless GPIO Integration: Plugs directly onto the Raspberry Pi pins, providing power and data without the need for an external power source or bulky HDMI cables.

• Responsive Resistive Touch: Allows for precise interaction using the included stylus, perfect for navigating small menus and virtual keyboards.

• Software Support: Fully compatible with official Raspberry Pi OS (Raspbian), Ubuntu, and RetroPie via easy-to-install drivers.

• Customizable Backlight: Features an onboard hardware switch or software-controllable brightness to optimize power consumption for battery-operated builds.

• High-Speed SPI: Optimized for performance, capable of pushing higher frame rates than standard generic SPI screens.

Technical Details

• Hardware Compatibility: Works with Raspberry Pi 4B, 3B+, 3B, 2B, and even the Pi Zero (via jumper wires or headers).

• Driver Architecture: Uses the LCD-show driver package, which allows for quick switching between the LCD and HDMI output via terminal commands.

• Pixel Density: Offers a sharp viewing experience for its size, suitable for text-heavy terminal work or basic image viewing.

• Touch Controller: Integrated XPT2046 touch controller chip ensures accurate coordinate mapping after a simple calibration.

• Power Efficiency: Draws only 160mA from the Pi's 5V rail, ensuring your system remains stable even when using a standard 2.5A power supply.

• Physical Protection: The PCB acts as a protective shield for the top of the Pi, and the screen features a durable resistive film.

• GPIO Pass-through: While it uses the SPI pins, several GPIO pins remain accessible for connecting additional sensors or buttons.

• Mounting Security: Aligning the headers ensures a secure mechanical fit that won't vibrate loose in mobile robotics applications.

• Refresh Rate Tuning: The driver supports overclocking the SPI bus to achieve up to 60fps for simple UI animations.

• Color Depth: 16-bit High Color (65K colors) provides vibrant icons and clear data visualizations.

• Stylus Accuracy: High-resolution resistive overlay prevents "ghost touches" often found in cheaper capacitive alternatives.

• Wide Viewing Angle: Optimized for top-down or slight-angle viewing common in desktop project enclosures.

• Heat Dissipation: Designed with a slim profile to allow airflow to the Pi's CPU, though heatsinks are still recommended for Pi 4 users.

• System Integration: Can be configured as a primary display or a secondary status monitor using FBCP (FrameBuffer Copy).

• Compact Footprint: Matches the credit-card size of the Raspberry Pi perfectly for a sleek, integrated look.
