4.3″ Primary gen4 Display CAPE for the BeagleBone Black with Capacitive Touch
The gen4 LCD CAPE range is specifically designed for the Beagle Bone Black (BBB). It provides a 4.3”, 5.0” or 7.0” primary display for the BBB for direct user interaction and information display.
Available in both Resistive Touch (GEN4-4DCAPE-xxT), Capacitive Touch (GEN4-4DCAPE-xxCT) and non-touch (GEN4-4DCAPE-xx) via special request – the non-touch version may be subject to MOQ and Lead Times. (xx refers to 43, 50 and 70 accordingly)
The 4DCAPE is not compatible with the previous Beagle Bone (Beagle Bone White), and can only be used with the Beagle Bone Black.
The 4DCAPE features an on-board Microchip AR1021 resistive touch controller (Resistive Touch version only), which talks to the BBB over I2C. This enables a robust and reliable resistive touch platform, compared to previous LCD CAPE models which used the BBB’s analog inputs, which were prone to external noise and open source software. The Capacitive Touch version utilises a Focaltech capacitive touch controller, which also communicates over I2C.
The Beagle Bone Black connects directly on to an adaptor CAPE, which then connects to the display module using a 30 way FFC ribbon cable, enabling multiple mounting options. Everything the LCD CAPE requires such as power and display signals are provided from the BBB directly, via the Adaptor and FFC ribbon cable.
Mounting of the 4DCAPE is achieved with the 4x 4mm mounting holes present on the Display Module (Resistive and Non-Touch), enabling standard screws to fasten the GEN4 4DCAPE 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.
