Raspberry Pi 4DPI-32-II

$54.95 USD

3.2″ Primary Display for the Raspberry Pi

The 4DPi-32-II is a 3.2″ 320×240 Primary Display for the Raspberry Pi, which plugs directly on top of a Raspberry Pi and displays the primary output which is normally sent to the HDMI or Composite output. It features an integrated Resistive Touch panel, enabling the 4DPi-32-II to function with the Raspberry Pi without the need for a mouse.

Communication between the 4DPi-32-II and the Raspberry Pi is interfaced with a high speed 48Mhz SPI connection, which utilises an on-board processor for direct command interpretation and SPI communication compression, and features a customised DMA enabled kernel.

The 4DPi-32-II is designed to work with the Raspbian Operating System running on the Raspberry Pi, as that is the official Raspberry Pi operating system. The new PIXEL addition to Raspbian is also supported.

Powered directly off the Raspberry Pi, this 3.2″ Touch panel allows effortless connection, and a single download package will get you up and running with a few simple steps. Please refer to the Datasheet for detailed information.

Product Availability Statement

Supply Commitment

4D Systems aims to supply its products for as long as possible, but cannot fully guarantee availability. This applies to modules, displays, components, and materials over long terms like 5–10 years.

Product Availability Conditions

4D Systems can only supply products while materials are available on the open market. Supply continues as long as demand exists and materials/components are available to produce viable products.

End of Life (EOL) Notifications

4D Systems provides End-of-Life (EOL) notifications, usually 3–6 months before the final run. In rare cases, sudden supplier issues may prevent notice, though alternatives are offered.

Ongoing Supply & Contact

4D Systems strives to continue supplying popular products and provide advance notice when items may become unavailable. For any questions regarding this statement, please contact us directly to discuss.

How do I choose the right display module for my project?

Start by identifying the demands of your product environment: required screen size, touch capability, operating conditions and UI complexity. Our consistent form-factor families allow you to select a module that fits your constraints today and upgrade performance later without redesigning your enclosure or PCB. Our documentation hub provides comparison tables to assist selection.

What is the difference between a smart display and a host-driven display?

Smart displays include an onboard processor that handles graphics, widgets, UI logic and drawing commands internally. This reduces load on your host MCU, simplifies code and often shortens development time dramatically. Host-driven modules require the host MCU to manage everything, which may be appropriate for minimal UIs but introduces more integration work.

Can I upgrade processors without changing my enclosure or PCB?

Yes. Our architecture is deliberately designed around footprint consistency. Most display families maintain identical mechanical and electrical footprints across multiple processor types, enabling generation-to-generation performance improvements without mechanical redesign.

Do you offer non-touch and touch options?

Yes. Many display families provide variants for non-touch, resistive-touch and capacitive-touch configurations. Capacitive-touch variants are recommended for modern, responsive UI experiences.
