This is a very small OLED display. The total size is about 37x12mm. Wires pictured are not included, just for demo purposes. Taking pictures of displays is really hard, in real life it looks crisp clear bright and blue, hazyness in the pictures is my rubbish photography.
I2C interface and runs fine on 5v
The driver is the SSD1306
There are already lots of "official" libraries available to run the SSD1306 display, so at this stage I'm not going to write my own, reinventing the wheel and all that. In your Arduino Library Manager just search for SSD1306. The SSD1306Ascii library is perhaps the simplest if you just want to display text, the u8g2 or u8glib libraries are big but quite complex, the Adafruit SSD1306 library is perhaps the most well known, there are plenty of other libraries there those are just the main ones.
Remember, this is 32px high display, if you chose a 64px high driver/library then it won't work properly.
Header may or may not already be soldered on depending on stock, if you need it without soldered on headerthen best ask first.
Have fun!
