2.7-Inch Monochrome OLED Graphic Display Module Kit – 128×64 Resolution

Description

If you’re a fan of our monochrome OLED displays but need something larger, the 2.7″ OLED Display will certainly impress you! With a high-contrast white OLED screen made of 128×64 individual pixels, each pixel is independently controlled, offering a crisp, sharp display that doesn’t require a backlight. This makes it not only more power-efficient but also results in incredibly high contrast for clear and readable text and graphics.

This display uses the SSD1325 driver chip and supports both 8-bit and SPI communication modes, though we recommend using SPI for simplicity and fewer connections—just 4 or 5 wires needed. It operates at 3.3V power and logic levels, but don’t worry, we’ve included a breadboard-friendly level shifter to allow compatibility with 5V logic devices, like Arduino.

Key Features:

• Large 2.7″ Diagonal Display: Perfect for larger projects where you need more screen real estate.
• OLED Technology: No backlight required, resulting in lower power consumption and better contrast. The pixels are individually lit, which contributes to the high contrast.
• SSD1325 Driver Chip: Easily controlled via SPI or 8-bit interface, allowing for flexible integration into your projects.
• Power Efficiency: Typically uses 50-150mA of current from the 3.3V supply, with a built-in boost converter to power the OLED pixels.
• Level Shifter Included: A 74HC4050 (or compatible) level shifter is included to convert 5V logic down to 3.3V, making it compatible with both 3.3V and 5V systems.
• Easy Mounting: The display comes with a bezel and 4 mounting holes for easy integration into your project.
• Customizable Communication: Choose between SPI and 8-bit mode, with instructions provided on how to switch modes by soldering.

Usage & Setup:

• This display requires a microcontroller with more than 1K of RAM because it buffers the full display. Our Arduino library provides example code for drawing text, graphics, bitmaps, and more.
• It uses about 1K of RAM for buffering, and despite the buffering requirement, the display is quick and responsive, perfect for real-time graphics and text rendering.
• OLED Wear & Tear: OLED displays use organic LEDs for each pixel, which means that if left on continuously for over 1000 hours, the pixels will start to dim. To preserve uniform brightness, it’s a good idea to turn off the display (set pixels to off) when not in use.

Dimensions & Specifications:

• Screen Dimensions: 2.9″ x 1.8″ x 0.2″ / 74mm x 46mm x 5mm
• PCB Dimensions: 3.3″ x 2.2″ x 0.05″ / 85mm x 58mm x 1.4mm
• Screen Weight: 32g

Whether you’re working on a large-scale project or need a high-contrast display for text and graphics, this 2.7″ OLED is the perfect choice. With a simple interface, low power consumption, and high clarity, it’s ideal for many applications like digital dashboards, sensors, and graphical displays.
