Five tiny rectangular OLED boards with white pixels and four-pin headers

Hosyond 0.91 Inch I2C OLED Display Module 128x32 White 5 Pcs

SKU CH-P79W-E9HTY

A pack of five 0.91-inch I²C OLED modules with 128×32 white pixels, 3.3–5 V supply and –40 to 85 °C operation

  • Compact 0.91 inch display fits tight builds
  • 128 x 32 pixel white OLED is self-illuminating
  • I2C interface uses only two signal pins
  • Operates from 3.3 V to 5 V logic levels
  • Five modules included for multi-node projects

0.91 Inch I2C OLED Display Pack

This pack contains five Hosyond 0.91 inch I2C OLED display modules. Each module features a 128 x 32 resolution with white self-illuminating pixels that require no backlight. The SSD1306 driver communicates over a simple I2C interface using only SDA and SCL lines plus power and ground. They are intended for makers adding compact readouts to Arduino, Raspberry Pi, ESP8266, ESP32 or STM32 projects.

Continuous Operation Characteristics

The OLED panels operate from a 3.3 to 5 V supply and are rated for an ambient range of -40 to 85 celsius. Because each pixel emits its own light, current draw scales with the number of lit pixels rather than a fixed backlight. The I2C bus keeps wiring minimal, reducing potential points of failure during long-running headless deployments. No active cooling is required for the bare board.

Integration Checklist

Verify that your host board provides a 3.3 V or 5 V rail and an I2C port with appropriate pull-up resistors. Confirm the available mounting area accommodates the 38 x 12 mm outline. Check that your software stack includes an SSD1306 driver for the target microcontroller. Ensure you can address the display on the default I2C address or have a method to change it if multiple devices share the bus.

Preguntas sobre este artículo

How much power does the SSD1306 OLED draw when running continuously?

The SSD1306 OLED operates at 3.3-5V with low power consumption and no backlight needed, making it suitable for all-day operation in battery-powered or embedded projects.

Which microcontroller pins and voltage levels are required to drive the I2C display?

Connect VCC to 3.3-5V, GND to ground, SCL to the clock line, and SDA to the data line on Arduino Nano, R3, Raspberry Pi 4B/3B+/3B/2B/Zero, ESP8266, ESP32, or STM32 boards.

Will the 0.91 inch 128x32 module work alongside older 5V Arduino boards without level shifting?

Yes, the module accepts 3.3-5V supply and uses I2C signalling compatible with classic 5V Arduino boards such as the R3, so it can be used directly without extra level-shifting circuitry.
