1.3″ Monochrome OLED Graphic Display

Display grafico OLED monocromatico di 1.3″

This Adafruit 128×64 pixel monochrome OLED graphic display is an excellent product for your projects.

Although the display is small (approximately 1.3″ diagonal), it is very readable thanks to the strong contrast of OLED technology. It consists of 128×64 individual white OLED pixels, meaning each pixel can be independently turned ON/OFF by the controller chip.

Since the display is self-emissive, no backlight is required, which reduces power consumption. This is one of the reasons why this display offers such high contrast.

There are two ways the driver chip (SSD1306) can communicate: I2C or SPI. Although the OLED itself requires 3.3V power and 3.3V logic levels, it can still be used with 5V systems thanks to the built-in 3.3V regulator and level shifting on all pins.

Power consumption depends on how much of the display is lit, but typically it draws around 40mA from a 3.3V supply. Inside the OLED driver there is a simple switched-capacitor charge pump that can convert 3.3V–5V into the higher voltage required by the OLED.

Please refer to the Adafruit SSD1306 OLED display guide if you intend to use this display with a Raspberry Pi.

You can also check the Arduino library tutorial and example code for graphics and text. A Raspberry Pi or microcontroller with at least 1KB of RAM is required because the display uses a framebuffer, but it is still very fast. The library supports text, pixels, bitmaps, rectangles, lines, and circles. The code can easily be adapted to other microcontrollers.

At the following link, you can find the Adafruit SSD1306 Python library, which works with OLED displays in both I2C and SPI mode on Raspberry Pi.

Breakout board dimensions:

• PCB: 35 mm × 35 mm × 5 mm / 1.4″ × 1.4″ × 0.2″
• Mounting hole spacing: 27 mm / 1.1″
• Mounting hole diameter: 2.5 mm / 0.1″
• Display: 23 mm × 35 mm / 0.9″ × 1.4″
• Weight: 8.5 g
• The board and chip use a 7-bit I2C address between 0x3C–0x3D, selectable via pre-crimped jumpers.

OLED display specifications:

• Screen diagonal: 1.30″
• Resolution: 128 × 64
• Color depth: Monochrome (White)
• Module construction: COG
• Module size: 34.50 × 35.00 mm
• Panel size: 34.50 × 23.00 × 1.45 mm
• Active area: 29.420 × 14.70 mm
• Pixel pitch: 0.23 × 0.23 mm
