gen4-4DPI-Adaptor
Overview and Purpose
Overview and Purpose
The gen4-4DPI-Adaptor is a compact, high-performance interface that connects 4D Systems gen4-4DPI Primary Displays directly to Raspberry Pi platforms. Designed for 4.3”, 5.0”, and 7.0” TFT modules with either resistive or capacitive touch, it enables high-speed 48MHz SPI communication with typical frame rates of up to 20 FPS. Fully compatible with all Raspberry Pi models, the adaptor ensures quick installation without the need for external power, drawing directly from the Raspberry Pi.
It features onboard EEPROM for HAT compliance and supports seamless display and touchscreen integration for industrial, commercial, and embedded applications.

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.
