4D Serial Pi Adaptor
Overview and Purpose
Overview and Purpose
The 4D Serial Pi Adaptor is a board designed to provide a serial interface in a convenient form factor, allowing the Raspberry Pi to connect to most 4D System display modules with a single 5-pin connection. The 4D Serial Pi Adaptor features a pass-through header design, enabling existing Raspberry Pi products to connect to the Raspberry Pi, as if the adaptor were not installed. The 4D Serial Pi Adaptor utilises only the serial port on the Raspberry Pi.
The 4D Serial Pi Adaptor comes with one 150 mm 5-way female-to-female jumper cable and one 5-way male-to-male adaptor.

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.
