1. Description
The gen4-IoD (Internet of Displays) series of is part of
the latest gen4 Range of modules Designed and
Manufactured by 4D Systems.
The gen4 series was designed specifically for ease of
integration and use, with careful consideration for
space requirements and functionality.
This specific gen4 module features a 2.4”, 2.8” or a
3.2” colour TFT LCD display, with Resistive Touch. It is
powered by the WiFi enabled ESP8266, which offers
an array of functionality and options for any Designer
/ Integrator / User.
The gen4-IoD range can be easily programmed using
4D Systems Workshop4 or the Arduino IDE installed
with the ESP8266 core.
The feature rich 4D Systems GFX4d library enables
speedy development of applications by providing
extensive primitive graphics functions, enhanced
graphics via Workshop4, SD card and touch routines,
integrated into a single library.
The on-board SD card socket enables the use of FAT16
or FAT32 formatted cards for extensive storage
capabilities.
The gen4-IoD series of Integrated Display Modules
features a 10 pin ZIF socket, designed for a 10 pin FFC
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.
