1. Description
The uOLED-128G2 is an impressive OLED display module in the 4D Systems microOLED graphics display range. Combining a resolution of 1.5” 128x128 pixels with 65K True to Life colours, this display module is perfect for animations, slideshows and other multimedia presentations. It is the ideal size for attractive embedded display applications.
This module flaunts a 1.5” state of the art Passive Matrix OLED (PMOLED) technology that is both crisp and superior to other display technologies. Driving the module and its peripherals is the GOLDELOX processor, a very capable chip which provides impressive graphics power, programmed with 4D Systems Workshop IDE Software.
4D Systems Workshop enables graphic solutions to be constructed rapidly and with ease due to its design
being solely for 4D’s graphics controllers.
The uOLED-128G2 has a modest but comprehensive range of features suited for an application requiring a bright eye catching display, an analog input, Dallas 1-wire sensor capability, audio generation, or simply digital I/O. This is truly an impressive little module.
