Fermion: Monochrome 0.91” 128×32 I2C OLED Display with Chip Pad

This OLED display module from DFRobot uses the SSD1306 driver chip, has 128×32 self-illuminating white pixels and adopts the back chip-mounting pad design.

Small in size, the length is 41mm and the width is only 12mm. With its compact size, simple wiring and low power consumption, it can be applied to many display applications, such as wearable display devices, mini game consoles, desktop widgets and more.

The display module adopts a high-contrast, low-power OLED display. Full-screen lighting consumes approximately 25mA (3.3V)/25mA (5V) and full-screen off power consumption: approx. 2mA (3.3V) 2mA (5V). It is compatible with controllers such as the Arduino Uno, Leonardo, ESP32/ESP8266, FireBeetle and so on.

Internal power-on reset processing, I2C communication methods and the chip-mounting pad, so that your welding line will be more convenient and simpler. The module has an ultra-narrow PCB design that is more flexible to match more applications.

Note: Turn the pixels off when you are not using the display to prevent darkening, which may cause brightness uniformity issues.
