1.3 Inch OLED Display Module I2C SH1106 128×64 4 Pin – White

About 1.3 Inch OLED Display (White)

This 1.3 inch OLED display is a monochrome 128×64 dot matrix module with white pixels on a black PCB, using the I2C interface. It gives you a larger, easier-to-read screen than the 0.96″ OLED while needing only 2 data pins. Compared to an LCD, an OLED has high brightness, self-emission (no backlight), a high contrast ratio, a slim outline, a wide viewing angle and low power consumption. The onboard voltage regulator makes it compatible with any 3.3V–5V microcontroller, such as ESP32, Arduino and Raspberry Pi.

Pin Definition

• GND: Power ground
• VCC: Power positive (3.3V–5V)
• SCL: I2C clock line
• SDA: I2C data line

Note: GND is the first pin on this module. Many 1.3″ OLEDs have VCC first, so double-check your wiring.

I2C Address Selection

The back of the module has an ADD_SELECT resistor marked 0x78 and 0x7A. These are 8-bit addresses. In most code and I2C scanners they appear as 7-bit addresses:

• 0x78 = 0x3C (default)
• 0x7A = 0x3D (move the resistor to the 0x7A side)

This lets you run two 1.3″ OLED displays on the same I2C bus.

Specifications

Library Support

This module uses the SH1106 driver. Use the U8g2 or Adafruit SH110X library. An SSD1306 library will show a shifted image or noise along one edge. In U8g2, pass the address as 0x78; in Adafruit SH110X, use 0x3C.

Applications of 1.3 Inch OLED Display
