user61695: As I wrote in title, I have Arduino Uno and Wemos (0.66” Across) OLED Shield which i bought along wemos d1 mini.
For some reason I want to use it with uno. but there are just 0.96 tutorials internet and I don't know which pins to connect. I would appreciate any help.
PINS UNDER blue stick are 
TX
RX
D1
D2
D3
so on..


user30175: The first thing I see when googling "0.66 lolin oled" is the link to https://wiki.wemos.cc/products:d1_mini_shields:oled_shield and their Get started guide. This yields the libraries to be used with it:

for the OLED: https://github.com/mcauser/Adafruit_SSD1306/tree/esp8266-64x48 with the dedicated test sketch
for the A & B buttons: https://github.com/wemos/LOLIN_OLED_I2C_Button_Library
