Frequently Asked Questions
Q: Is this I2C OLED display module compatible with Arduino boards?
A: Yes, the 0.91-inch I2C SSD1306 OLED display module is fully compatible with Arduino (Uno, Nano, Mega, etc.), as well as ESP8266, ESP32, Raspberry Pi, and other microcontrollers that support I2C communication. Popular libraries such as Adafruit SSD1306 and U8g2 work seamlessly with this module.
Q: Can this OLED module run on 3.3V logic systems?
A: Absolutely. The module supports an operating voltage of 3.3V to 5.0V DC, making it compatible with both 3.3V and 5V logic systems without the need for a level shifter in most applications.
Q: What is the I2C address for this SSD1306 OLED module?
A: The default I2C address for this SSD1306-based OLED display module is typically 0x3C. Some boards may allow address switching to 0x3D via a solder jumper. Always check your specific module's datasheet or test with an I2C scanner sketch to confirm the address.
Q: What display types are available for this module?
A: This OLED display module is available in White and Blue pixel color variants. Both versions use the same SSD1306 driver and I2C interface, so they are functionally identical — the difference is purely the color of the emitted light from the OLED pixels.
