A compact 1″ diagonal OLED display with 128×32 white pixels driven by the SSD1306 controller. Each pixel is individually lit, delivering sharp, high-contrast graphics with no backlight needed — resulting in excellent readability and low power consumption.
Communicates via SPI (4–5 pins required) and includes an onboard 3.3 V regulator and level shifter, so it works directly with 5 V microcontrollers like Arduino. Average power draw is around 20 mA from the 3.3 V supply.
Key Features
- 128×32 White OLED Pixels – Crisp, high-contrast monochrome display
- SSD1306 Driver – Well-supported controller with SPI interface
- Onboard Regulator & Level Shifter – 5 V compatible out of the box
- No Backlight Required – Self-emitting pixels for lower power draw
- Built-In Charge Pump – Generates OLED drive voltage from 3.3–5 V input
- Low Power – Approximately 20 mA average from 3.3 V

Jargon buster
Plain-language definitions for the technical terms used above.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- OLED
- OLED stands for organic light-emitting diode, a display type where each pixel produces its own light. It matters because OLED screens are thin, high-contrast and easy to read for small status displays, but they can be more sensitive to image burn-in than some other display types.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
