4Duino-24 Display Module

The 4Duino-24 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-24 is an ATmega32U4 8-bit micro controller from Atmel. The same microcontroller is found on popular Arduino Leonardo. 4Duino-24 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-24 features the popular ESP8266 Wi-Fi module which is pre-programmed with the AT command set firmware, enabling the 4Duino-24 to have many Wi-Fi capabilities right out of the box.

The 4Duino-24 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-24 is easily programmable with the Workshop4 IDE and its 3 different 4Duino-24 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-24 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-24 comes with the main Through-Hole headers unmounted. These need to be soldered by the Customer. Please refer to the Datasheet for more information.
