This display is made of 128x32 individual OLED pixels.
It communicates with Raspberry pi or Arduino series products via I2C protocol.
Compatible with most of MCU which support I2C protocol communication.
There are mounting hole and female pin header on the PCB, so that you can fix it to Raspberry Pi with screws and nuts.
It is compatible with Adafruit OLED liberary.

  • Question: why does it not show anything that I've tried as your instruction?
    • Answer: Please make sure you have already open your i2c function and you can use this command to detect whether it has been turned on already.
    • i2cdetect -y 1
