4Duino 2.4" TFT LCD  IoT Display Module

The 4Duino is an ArduinoTM compatible display module with built in 240x320 resolution TFT LCD Display with Resistive Touch, and Wi-Fi capabilities, perfect for IoT (Internet of Things) Applications.

At the heart of 4Duino is an ATmega32U4 8-bit micro controller from Atmel. The same microcontroller is found on popular Arduino Leonardo. 4Duino features a 2.4” colour TFT LCD display, with resistive touch. It is powered by the feature-rich 4D Systems Picaso Graphics Processor, which offers an array of display functionality and options for any Designer/ Maker. In addition, the 4Duino features the popularESP8266 Wi-Fi module which is pre-programmed with the AT command set firmware, enabling the 4Duino to have many Wi-Fi capabilities right out of the box.

The 4Duino also features an on-board microSD connector, and headers in the layout of an Arduino, including power pins (5V, 3.3V, GND and VIN), 20 digital IO pins, of which 7 can be used PWM outputs and 12 pins have Analog input capabilities.

The 4Duino is easily programmable with the Workshop4 IDE and its 3 different 4Duino based development environments.

The Workshop4 IDE has new functionally added, and is now able to program the on board Atmel processor using the popular Arduino programming language, just like the popular Arduino IDE, but with the added dimension of graphics – with the aid of the 4D Systems Picaso GPU. Creating Arduino based GUI’s does not get any easier.

The 4Duino design has incorporated a TFT LCD Touchscreen Display and Wi-Fi solution with the intention of providing a flexible and hugely capable hardware platform. This will enable Markers and Designer to significantly improve the quality and the scope of their projects, and do so rapidly with the aid of the 4D Systems Workshop4 IDE.

Introducing 4D Systems' All New Workshop4 IDE

Supports multiple development environments, to cater for different user requirements and skill level.

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.

Workshop4 has an additional three development environments specifically for the 4Duino, allowing the user to program the Atmel processor using the familiar Arduino style code from inside the Workshop4 IDE itself.

This environment enables the
user to write 4DGL code in its
natural form to program the
display module.


ViSi - Genie

An advanced environment
that doesn't require any
coding at all, it is all
automatically for you.
lay the display out
with the 
objects you want
(similar to 
ViSi), set the
events to drive 
them and
the code is written 
you automatically. ViSi
Genie provides the latest
rapid development
experience from
4D Systems.



This environment is also
provided to transform the
display module into a
slave serial display module,
allowing the user to control
the display from any host

microcontroller or device
with a serial port.

A visual programming
experience that enables
drag-and-drop type

placement of objects
to assist with 4DGL code
generation and allows

the user to visualise how
the display will look while
being developed
