128x64 resolution SPI communication or I2C communication can be switched by configuring three resistors R3 R4 R5. The driver chip for this screen is SSD1309, which supports 4-wire SPI, I2C and 8-bit interfaces. It does not support 3-wire SPI. 2.42 inch OLED display module for IIC communication, it is necessary to move the resistor on R4 to R3, and R5 is soldered with 0 ohm resistor. 2.42" OLED Interface selection : SPI(Factory Setting) or IIC(You need to move the resistor R4 to R3, and solder R5 with 0 ohm resistor). 2.42" inch OLED display resolution: 128 * 64; Driver IC: SSD1309; Diagonal Screen Size: 2.42 inch.
