5.0″ gen4 Series Intelligent Display Module with DIABLO16 Graphics Controller with Hardware Interface for Arduino

The gen4 5.0” Diablo16 Integrated Display Modules are part of the latest gen4 series of modules Designed and Manufactured by 4D Systems.

This hardware bundle includes the 4D Arduino Adaptor Shield II which allows fast and easy hardware interface to any Arduino board with the standard Arduino Headers and allows you to quickly and easily add a full colour HMI to your Arduino project.

The gen4 series was designed specifically for ease of integration and use, with careful consideration for space requirements and functionality.

These specific gen4 modules feature a 5.0” colour TFT LCD display, and come with options for Cover Lens Bezel (CLB), and resistive touch. They are powered by the well-known 4D Systems Diablo16 Graphics Processor, which offers an array of functionality and options for any Designer / Integrator / User.

The 5.0” Diablo16 Integrated Display Module features a TFT LCD Display, is capable of Touch Detection, microSD memory Storage, GPIO and Communications, along with multiple millisecond resolution timers, and Audio Generation.

The gen4 Series is 100% compatible with the Workshop4 IDE and its 4 different development environments, providing the User with a wealth of options for programming and controlling their system.

The gen4 series of Integrated Display Modules features a 30 pin ZIF socket, designed for a 30 pin FPC cable, for easy and simple connection to an application or mother board, or for connecting to accessory boards for a range of functionality advancements.

The gen4 series of modules has been designed to minimise the impact of display related circuitry, and provide a platform suitable for integration into a product. Application boards can sit flush on the back of the gen4 if required, as the display related electronics sit inside the plastic mounting base, leaving the application board surface clear for User circuitry.

Workshop4 is a comprehensive software IDE for Microsoft Windows that provides an integrated software development platform for all of the 4D family of processors and modules. The IDE combines the Editor, Compiler, Linker and Downloader to develop complete 4DGL application code.

All user application code is developed within the Workshop4 IDE.


Workshop4 includes four development environments for the user to choose based on application requirements or even user skill level.


Make complex widget design, simple.

Smart Widgets Editor is a powerful utility which enables the generation of Smart Widgets.

  • Users can create complex widgets with up to six layers, including the layer for the base image. The order of the layers can be arranged as desired.
  • Each layer can contain one or more images arranged in sequence that can be manipulated in a variety of ways. Image manipulation options include horizontal motion, vertical motion, and angular motion. Additionally, the transparency of a layer can be set.
  • Two or more layers can be linked to produce synchronized movements of images. This enables the generation of complex widgets with multiple moving parts. Clockwork feature is also supported. This enables users to quickly generate clock widgets.
  • Each layer can have a numeric part which can display numbers in various fonts and formats. Alternatively, the numeric part can be a fixed sequence of text.
  • The output frames can be utilized using any of the supported Workshop4 environments.


Genie Magic is an extension to ViSi-Genie, which is available in Workshop4 PRO. Genie Magic allows the User to add 4DGL code to various points in the ViSi-Genie backend code, which allows Users to take full advantage of the power of 4DGL, while retaining the speed and convenience of ViSi-Genie and its defined communication protocol.

Genie Magic allows you to enter 4DGL code in the form of Events, Code and Objects, along with various touch related additions too, giving you to the power to achieve advanced GUI’s in ViSi-Genie without having to write the full code yourself.

Genie Magic is fully supported by the genieArduino and geniePi libraries, making communication with an Arduino or Raspberry Pi host even more powerful.

When using Genie Magic in combination with the Smart Widget Editor, it is possible to use the Smart Widgets Editor tool and Smart Widgets to create other graphical user interface elements such as:

  • Dropdown Menu

  • Side Menu

  • ‘Carousel Slider’

  • List Box

  • Dock Menu
  • Quarter-Rotary Menu

  • Fading Slide-To-Unlock Button

  • Spectrum With Transparency

  • And Many Others



Workshop4 is a Windows-only product. It is compatible with Windows 8 through to Windows 11.

Note some older OS such as ME, Vista, XP and 7 have not been tested for some time and are not supported by Microsoft anymore; however, they may still work.
Legacy support updates for the older OS may not be possible, depending on what issues are found. For best results, run a current Windows OS.

It is possible to run Workshop4 under a VM on Linux or Mac. However, it is up to the User to set this up.
