What is it?

Introducing the Mini Transparent Cube OLED Display Screen Breakout — a cutting-edge innovation that combines the precision of a tiny 0.42" OLED screen with the optical properties of a 1cm cube light prism. This unique setup allows images and text from the OLED screen to be reflected within the transparent cube, creating a captivating and miniature display that appears to float in space. See demo video below! Despite its small size, this display offers a range of creative and functional applications.

Key Features:

• Transparent Display: The transparent nature of the cube allows users to view the content from multiple angles, creating an immersive and almost holographic experience.

• Ultra-Compact Design: With a 1cm cube prism screen, this product is perfect for applications where space is limited or where a small, intricate display is needed.

The display board has the following pinouts:

• 3V3: 3.3V Voltage Input
• SCL: I2C Clock Signal
• SDA: I2C Data Signal
• GND

To use it, connect to a microcontroller via I2C (SCL, SDA, 3V3 and GND). It can be used with open source libraries such as: U8g2

Important: To use the library, you need to edit the u8x8_d_ssd1306_72x40.c file and modify the following line to invert the image:

• Change U8X8_C(0x0a1) to U8X8_C(0x0a0)

This adjustment ensures that the image displays correctly in the cube. If not modified, the image will appear inverted.

When using the above library, be sure to use the following constructor: U8G2_SSD1306_72X40_ER_F_HW_I2C u8g2(U8G2_R2, / reset=/ U8X8_PIN_NONE); // EastRising 0.42" OLED

Potential Use Cases:

• Miniature Collectibles Display: Ideal for enhancing small collectible items, such as figurines, model cars, or rare artifacts. The Miniature Transparent Cube OLED Display can be placed alongside these items to showcase additional information, like names, stats, or historical data, in a visually appealing way without overshadowing the collectible itself.

• Wearable Tech Display: Due to its small size, this transparent cube display can be incorporated into wearable technology, such as custom jewelry or smart accessories. It can display notifications, small animations, or other relevant data, making it both functional and stylish.

• Interactive Control Panels: The Miniature Transparent Cube OLED Display can serve as a dynamic button in control panels for high-tech devices or custom projects. The transparent display can change its imagery based on the function it is assigned to, providing both visual feedback and an interactive touchpoint. For example, in a custom-built keyboard or control interface, each cube can display icons or symbols representing different commands or modes.

• Gaming Accessories: Gamers can use the cube display as a button in custom gaming controllers or accessories. The transparent cube can display game-specific icons or animations, and pressing the cube could trigger special actions in the game. This provides a tactile and visual enhancement to gaming setups, particularly for games requiring multiple custom inputs.

By using the Miniature Transparent Cube OLED Display as a button, you can create interactive, visually engaging, and functional interfaces across various applications, from consumer electronics to wearable tech. Its small size and transparent design make it an ideal choice for innovative and compact input solutions.
