2.42 Inch White LED OLED Display 7 Pin SPI 128 x 64 Pixels (D23)

u8g2.clearBuffer(); u8g2.setFont(u8g2_font_ncenB14_tr); u8g2.drawStr(0, 22, "Arduino Due"); u8g2.setFont(u8g2_font_6x12_tr); u8g2.drawStr(0, 42, "SSD1309 SPI"); u8g2.drawStr(0, 58, "128x64 Display"); u8g2.sendBuffer(); delay(1000); } ESP32 and Arduino Compatibility Notes This OLED display is especially well suited for ESP32 projects because ESP32 boards use 3.3V logic. Connect the display to the ESP32's SPI pins, provide 3.3V power, and use a compatible display library such as U8g2 or another SSD1309-capable graphics library. Arduino compatibility depends on the board being used. 3.3V Arduino boards are the easiest match. When using a 5V Arduino board, use a 3.3V power source and logic level conversion on the signal lines. Do not connect this display directly to 5V logic pins. Bright, Compact Display for Embedded Electronics The 2.42 inch SSD1309 OLED module is a great choice when you need a readable display that is larger than the typical small OLED screen but still compact enough for modern embedded electronics. It is a practical display option for ESP32 developers, electronics students, Arduino users, repair benches, and anyone adding a simple visual interface to a custom circuit.
