Wi-Fi-enabled 0.9-inch colour LCD targets IoT

November 09, 2017 // By Julien Happich
4D Systems' IoD-09 series full colour 80x160 pixel TFT LCD display module (0.9-inch diagonal) comes with integrated Wi-Fi and a microSD/HDC slot. It can display full colour images, animations and icons and is available in two variants: through-hole (IoD-09TH) and surface mount (IoD-09SM) for mass production integration.

The module is designed around the ESP8266 System-On-a-Chip (SoC) 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 1-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). It operates 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 (GUI).

A starter kit is available which includes an IoD display module, the 4D-UPA programmer and a 4GB micro-SD card.
