0.91 Inch SSD1306 128x32 I2C OLED Display Module

The UG-2832TSWEG02 is a 0.91-inch monochrome OLED display module built around the SSD1306 driver IC. It offers a 128×32 pixel passive-matrix panel with self-illuminating white pixels, eliminating the need for a backlight and delivering high contrast, wide viewing angles of over 160 degrees, and low power consumption compared to conventional LCD modules. The module communicates over an I2C interface, using only two signal lines (SDA and SCL) in addition to power and ground, which simplifies wiring with Arduino, Raspberry Pi, ESP32, and other microcontrollers. It operates from a 3.3V to 5V DC supply, and the panel’s active area measures 22.384 × 5.584 mm while the module itself measures 38.0 × 11.9 × 3.9 mm (excluding the header height). Full-screen operation consumes approximately 80mW, and the display supports a frame rate of 150 frames per second with 1/32 duty cycling. The module is supplied with a 14-pin flat flexible cable (FFC) for connection, making it suitable for compact enclosures where a soldered header is impractical. With an operating temperature range of -30°C to +70°C, this I2C OLED display is a practical choice for wearable devices, portable instruments, medical equipment, sports monitors, and embedded status displays that require a small, bright, and low-power screen.
