Introducing the Miniature 0.42-Inch 72x40 Pixel OLED Screen! As it measures only 12.6mm x 13.3 x 2.4, it is probably the smallest OLED screen on the market! Since it is so small, standard headers would be an overkill in terms of size, so I designed it with castellated pads to save space. Although you might see the same screen out on the market, it's always with standard headers, which defeats the purpose of the small size since headers take up almost the same amount of real estate as the screen itself! I also used 0201 passives! (It is definitely a labor of love and worth the trouble, since the outcome speaks for itself). See pictures above and video below.
The Miniature OLED Screen caters to a wide range of use cases and applications, making it an essential component for any DIY project. Unleash Your Creativity! Here are just a few potential use cases that showcase its versatility:
Miniature Gaming Consoles: Create your own pocket-sized gaming console with the Miniature OLED Screen. Design retro-style games or display scores, level indicators, and character information for a nostalgic gaming experience on a tiny canvas.
Wearable Devices: Embed this miniature OLED screen into your wearable tech projects, such as smartwatches, fitness trackers, or augmented reality glasses. It provides a compact yet informative display for notifications, time, health data, and more.
IoT (Internet of Things) Applications: Utilize the OLED screen as a compact user interface for your IoT devices. Control and monitor connected devices, display sensor data, or showcase real-time information on temperature, humidity, or energy consumption.
Portable Instrumentation: Incorporate this screen into your DIY instruments or measurement tools, such as multimeters, oscilloscopes, or environmental sensors. Display real-time data, waveforms, readings, and calibration information for quick and easy analysis.
Wearable Art and Jewelry: Merge technology and aesthetics by integrating this OLED screen into wearable art or jewelry pieces. Display intricate patterns, animations, or personalized messages, allowing you to express your creativity in a unique and interactive way.
To use it, connect to a microcontroller via I2C (SCL, SDA, RESET, VCC and GND). See the last photo above for a pinout diagram.
It can be used with open source libraries such as: https://github.com/olikraus/u8g2
Notes: This board runs on 3.3V VCC and logic. When using the above library, be sure to use the following constructor:
U8G2_SSD1306_72X40_ER_F_HW_I2C u8g2(U8G2_R0, / reset=/); // EastRising 0.42" OLED
