0.9" Internet of Displays (IoD) Display Modules

The IoD-09 (Internet of Displays) series is a range of miniature display modules Designed and Manufactured by 4D Systems.

The IoD-09 modules feature a full colour 0.9” TFT LCD display. They are powered by the WiFi enabled ESP8266, which offers an array of functionality and options for any Designer / Integrator / User.

The IoD-09 modules can be easily programmed using 4D Systems Workshop4 or the Arduino IDE installed with the ESP8266 core.

The feature rich 4D Systems GFX4dIoD09 library enables speedy development of applications by providing extensive primitive graphics functions, enhanced graphics via Workshop4, SD card access, and much more, all 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 IoD-09 modules feature 12 pads, 6 on each end, for easy and simple connection to an application or mother board, or for connecting to accessory boards for a range of functionality advancements. The IoD-09TH features Through Hole (TH) pads with male pin headers mounted, and the IoD-09SM features Surface Mount (SM) pads.

This range of modules has been designed to minimise the impact of display related circuitry, and provide a platform suitable for integration into a product.

The IoD-09 modules can act as master or slave devices, they can be effortless connected to the internet, can display a raft information and graphics, along with the capability to communicate to SPI, I2C, and/or 1-wire devices, as well as having general GPIO for digital control/input.

Models in this size:
IoD-09TH (0.9" TFT LCD module with Through Hole interface)
IoD-09SM (0.9" TFT LCD module with Surface Mount interface)

4D Systems' Workshop4 IDE

Workshop4 delivers a comprehensive interface enriched with features for optimal software development for any user.

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 has been expanded to enable customers to write Arduino style code directly in the IDE, and program Arduino compatible modules directly. Coupled with 4D Systems graphics capabilities, the combination allows extended functionality over using the Arduino IDE alone, when programming compatible 4D Systems modules.
