Fermion 0.91 Inch I2C OLED Display Breakout Board

The Fermion Monochrome 0.91 Inch I2C OLED Display Breakout (DFR0648) is a compact, self-illuminating display module perfect for a wide range of electronic projects. This board utilises the SSD1306 drive chip and features a high-contrast, low-power OLED screen with 128x32 bright white pixels. Its back chip-mounting pad design contributes to a remarkably small form factor, measuring just 33mm in length and 20mm in width, making it ideal for space-constrained applications.

One of the key advantages of this display is its simple I2C communication interface, which requires minimal wiring and is compatible with popular development boards including Arduino UNO, Leonardo, ESP32, ESP8266, and FireBeetle-M0. The module supports a 3.3V to 5V voltage input range and includes internal power-on reset processing, simplifying your setup and integration.

Key Features & Applications

With its controllable pixels and extremely low power consumption, this OLED breakout is exceptionally versatile. It can clearly display two rows of 16-pixel characters, making it suitable for showing sensor readings, status messages, or simple graphics. Its small size and lightweight design (just 9 grams) open up possibilities for wearable technology, portable gadgets, and miniaturised consoles.

Typical applications include building desktop weather stations, digital thermometers, kitchen scales, air quality monitors, and mini game consoles. It is also an excellent choice for entry-level makers looking to add a clear, readable display to their first projects without complex soldering, thanks to its standard solder holes.

The package includes the monochrome OLED display and a set of 2.54mm pitch chip-mounting pins, providing everything you need to get started. Combine functionality, ease of use, and a professional look for your next prototype or finished product with this reliable display module.
