Diagonal Screen Size: 2.42 inch
_ Driver IC: SSD1309
_ 2.42 inch OLED display module of 128x64 resolution in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.
_ SPI communication or I2C communication can be switched by configuring three resistors R3 R4 R5.
_ For IIC communication, it is necessary to move the resistor on R4 to R3, and R5 is soldered with 0 ohm resistor.
