7.0″ Gen4 Primary Display for the Raspberry Pi
The gen4-4DPi range are Primary Display’s for the Raspberry Pi A+, B+, Pi2, Pi3, Pi3 B+, Pi4, Pi Zero and Pi Zero W, which display the primary output of the Raspberry Pi, like what is normally sent to the HDMI or Composite output. It features an integrated Resistive Touch panel or Capacitive Touch panel, enabling the gen4-4DPi to function with the Raspberry Pi without the need for a mouse.
Communication between the gen4-4DPi 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. This combination allows this display to output high frame rate compared to other SPI display solutions, when displaying a typical image/video, and can achieve higher depending if the image can be compressed.
The gen4-4DPi is designed to work with the Raspbian Operating System running on the Raspberry Pi, as that is the official Raspberry Pi operating system. It is also compatible with Pixel and Scratch.
The gen4-4DPi range connects to the Raspberry Pi’s 40 pin header using the gen4-4DPi Adaptor, which then connects to the gen4-4DPi display module using a 30-way FFC Cable.
Mounting of the gen4-4DPi is achieved with the 4x 4mm mounting holes present on the Resistive Touch Display Modules, enabling standard screws to fasten the Gen4-4DPi as required, or via the adhesive supplied on the Cover Lens Bezel which is part of the Capacitive Touch version.

Frequently Asked Questions
Find quick answers about our display modules, embedded integration, customization capabilities, and system compatibility.
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.
