Fermion: Monochrome 0.91” 128x32 I2C OLED Display with Chip Pad (Breakout)

This OLED display module incorporates the SSD1306 drive chip, featuring 128x32 self-illuminating white pixels. Its compact design measures 41mm in length and just 12mm in width, making it ideal for use in various applications such as wearable display devices, mini game consoles, and desktop widgets. With its small size, straightforward wiring, and low power consumption, this module is versatile and efficient.

Utilizing a high-contrast, low-power OLED technology, the display module consumes approximately 25mA at full-screen illumination at both 3.3V and 5V, while power consumption drops to about 2mA when the screen is off. It boasts compatibility with multiple controllers, including Arduino UNO, Leonardo, ESP32/ESP8266, and FireBeetle-M0. The module's internal power-on reset processing and I2C communication ensure seamless operation.

The chip-mounting pad design facilitates easier and more convenient soldering, while the ultra-narrow PCB enhances flexibility across a range of applications. To maintain pixel brightness uniformity, it's advisable to turn the pixels off when the display is not in use, thus preventing prolonged use of specific pixels and potential darkening.
