This OLED is really small, just 0.91”. It is made of 128x32 individual blue OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast.
It is compatible with any 3.3v-5V microcontroller, such as the Arduino, ESP32, STM32, RP2040, and others.
