4D adds smallest 0.9in display module to Internet of Displays range

Miniature IoT projects are the target for 4D Systems’ new Internet of Display (IoD) modules. The IoD is 4D’s range of miniature feature-rich displays that offer small colour displays with integrated wi-fi and a microSD/HDC slot.

Powered by the wi-fi enabled ESP8266, the IoD-09 is the 0.9-inch series of full colour, 80 x 160 pixel TFT LCD. It can display full colour images, animations and icons.

The new modules come in two variants: through-hole (IoD-09TH) and surface mount (IoD-09SM). 4D says the through-hole module can potentially be integrated quickly and easily into any product while the surface mount module is aimed at mass production integration.

The module is designed around the ESP8266 system-on-a-chip from Espressif. It comes with 802.11 b/g/e/I support as well as WPA/WPA2, WEP/TKIP/AES and STA/AP/STA+AP/P2P operational mode support. There are six GPIOs available allowing digital input/output as well as various communication protocols.

Available interfaces include SPI, I2C, UART and one-wire communications. A micro-SD slot allows the use of off-the-shelf high capacity memory cards from 4GB to a maximum of 32GB. FAT16 and FAT32 file accesses are supported. The module also comes with 4Mbit of flash memory for user application code and data, as well as 128Kb of SRAM (80Kb available for the user).

4D recommends the IoD-09 series is powered from a 4.0V to 5.5V source with +1Amp current capability for display stability.

The IoD-09 can be programmed with the 4D Systems Workshop4 integrated development environment (IDE) or through the Arduino IDE. Workshop4 provides powerful graphics using the GFXdloIoD09 graphics library specifically for the IoD-09 series through a drag and drop style graphical user interface. The graphics library can be downloaded from the company’s github repository, which also comes with source demo applications. Workshop4 is available as a free download from 4D’s website and requires a one-off licence that can be bought from the company.

The IoD-09 starter kit, which is available on 4D’s website, comes with an IoD display module, 4D-UPA programmer and a 4GB micro-SD card.
