4Duino 2.4″ TFT LCD IoT Display Module
The 4Duino is an ArduinoTM compatible display module with built in 240×320 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.

NOTE: 4Duino comes with the main Through-Hole headers unmounted. These need to be soldered by the Customer. Please refer to the Datasheet for more information.

WORKSHOP4 IDE
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.
DEVELOPMENT ENVIRONMENTS THAT SUITS ANY APPLICATION & USER LEVEL
Workshop4 includes four development environments for the user to choose based on application requirements or even user skill level.


WORKSHOP4 PRO
Make complex widget design, simple.
Smart Widgets Editor is a powerful utility which enables the generation of Smart Widgets.
GENIE MAGIC
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:
