0.95 INCH OLED Display Features
OLED displays are high contrast and high-resolution displays, so they provide a good readability for users. There is no backlight on OLED, and it uses independent-illuminated pixels. So it is thinner, and more elegant in compare to LCDs.
This 0.95-inch colorful OLED is graphic type, the resolution is 96×64 pixels and the chip driver is SSD1331.
You can download the datasheet of this module here.

Is it possible to have a step by step on using this oled device within a seperate project. Sorry I am an old man newbie.
Thanks
Hi dear.
that is my honer to help you.
which part is difficult to do?
let me know what do you want to do with this OLED?
