This is easy to use OLED display, 0.96” screen size, 128x64 resolution and SSD1306 driver. You can connect to it via I2C (despite of PCB description it’s address is 0x3C not 0x78). Easy programming on Arduino. You can use Adafruit’s SSD1306 library. To make it easy example project can be downloaded from GitHub.

It is PlatformIO project, that mean, it should be easy to compile.
