An interesting find on Aliexpress: a slightly larger Arduino Nano board with an in-built 0.91″ OLED display, 128×32, I2C. The driver chip is the SSD1306.
Three libraries were needed to set it up and test it with a new sketch, but it works OK now. It could come handy for debugging comms or for monitoring program flow.
It is slightly larger than a normal Nano board.
The active area of the display is close to 25×10 mm.
There are many examples included with the libraries:

https://github.com/adafruit/Adafruit_BusIO
Keep in mind that these Adafruit libraries will take up almost 14 kB of flash. You can also try the u8g2 library.
