Frequently Asked Questions
Q: Is this SSD1306 OLED module compatible with Arduino UNO and Nano?
A: Yes! The SSD1306 0.91-inch SPI OLED module is fully compatible with Arduino UNO, Nano, Mega, ESP8266, ESP32, and most other popular microcontroller boards. Simply connect via the 7-pin SPI interface and use a supported library such as the Adafruit SSD1306 library to get started quickly.
Q: What is the difference between the White and Blue screen variants?
A: Both variants use the same SSD1306 driver and 128×32 resolution. The only difference is the pixel emission color — the White version displays bright white pixels on a black background, while the Blue version displays vivid blue pixels. Both offer excellent contrast and visibility.
Q: Does this module require a separate power supply or backlight?
A: No separate backlight is needed. OLED displays are self-emissive, meaning each pixel produces its own light. The module operates on 3.3V to 5V, making it directly compatible with most Arduino and microcontroller logic levels without any additional components.
