Adafruit Monochrome 1.12″ 128×128 OLED Graphic Display – STEMMA QT / Qwiic

Looking for Adafruit Monochrome 1.12″ Display? Adafruit Monochrome 1.12″ 128×128 OLED Graphic Display – STEMMA QT / Qwiic is available at Zbotic with fast shipping across India.

This OLED goes out to all the fans who want more pixels in a smaller size! Normally our 128×64 OLEDs are the biggest ones we’ve stocked that can use I2C. This one is a whopping 128×128 pixels in crisp monochrome.

This display is a petite 1.12″ diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128×128 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like these miniature displays for their crispness!

The driver chip, SSD1107 can communicate in two ways: I2C or SPI. The OLED itself requires a 3.3V and 12V power supply and 3.3V logic levels for communication. We include a 3.3V regulator and 12V boost converter, and all pins are fully level shifted so you can use them with 3V or 5V devices!

If you are using I2C, we’ve included SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don’t even need to solder! Plug and play with any board that has a Qwiic or STEMMA QT connector for effortless prototyping and development. QT Cable is not included, but we have a variety in the shop.

This display, being 128×128 pixels, requires 128 * 128 = 2KB of SRAM just to buffer the display. So you can’t use it with a small chip such as the Arduino UNO (ATmega328 or 32u4). Pick a microcontroller or microcomputer with 16KB+ RAM – a SAMD21, SAMD51, ESP, nRF52, Teensy, etc will do an excellent job. As long as you have an I2C or SPI interface available, you’re good to go – SPI will be much faster but I2C requires fewer pins.

We have both Arduino and CircuitPython support for this display chipset (SH1107).

Please note that OLED displays are made of hundreds of…OLEDs! That means each pixel is a little organic LED, and if it’s kept on for over 1000 hours it’ll start to dim. If you want to keep the display uniformly bright, please turn off the display (set the pixels off) when it isn’t needed to keep them from dimming.

Specification:

1. Diagonal Screen Size：1.12″
2. Number of Pixels：128 × 128
3. Colour Depth： Monochrome (White)
4. Module Construction: COG
5. Active Area (mm)：20mm x 20mm
6. Pixel Size (mm)：0.15 x 0.15 mm
7. Duty：1/64
8. Brightness ( cd/m2): 100 (Typ) @ 12V
9. Display current draw is completely dependent on your usage: each OLED LED draws current when on so the more pixels you have lit, the more current is used. They tend to draw ~35mA or so in practice but for precise numbers, you must measure the current in your usage circuit.

Frequently Asked Questions

How do I wire this display for I2C communication?

Use a STEMMA QT or Qwiic cable to connect the module’s four-pin port (SDA, SCL, 3–5 V, GND) directly to your microcontroller’s I2C header. No soldering is required.

Is an external backlight or contrast adjustment needed?

No. Each white OLED pixel is self-emissive, so the module produces its own light and automatically manages contrast via the SSD1327 driver.

Which software libraries support this 128×128 OLED?

For Arduino use the Adafruit SSD1327 library in combination with Adafruit GFX. In CircuitPython or MicroPython, import the adafruit_ssd1327 module to drive graphics and text.
