Grove - OLED Display 1.12" is an OLED monochrome 128×64dot matrix display module with Grove 4pin I2C Interface .The characteristics of this display module are high brightness, self-emission, high contrast ratio, slim outline, wide viewing angle, wide temperature range, and low power consumption. It has bigger screen and uses all the columns from the SSD1308 chip so that it can display more contents than the OLED 96×16.
Features
- Grove compatible
- Small size
- I2C Interface
- Low power consumption
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

Introduction
LED 128×64 Display module is an OLED monochrome 128×64dot matrix display module with Grove 4pin I2C Interface.Comparing to LCD, OLED screens are way more competitive, which has a number of advantages such as high brightness, self-emission, high contrast ratio, slim / thin outline, wide viewing angle, wide temperature range, and low power consumption. It has bigger screen so that it can display more contents than the OLED 96×96.
Model:OLE35046P
Features
- Grove compatible interface
- Communicate Mode:I2C
- Low power consumption
- Display Color: White
- Wide range of operating temperature:-20℃~70℃
Cautions
Please notice: heavy impact or stress on the OLED will cause the breakdown of screen..

Usage
The OLED128*64 uses all the pins of SSD1308 chip, the default original point is on the top left corner. You can also change the original point by adjusting the program and in order to display your desired patterns. For more details, please consult File:SSD1308_1.0.pdf and File:LY190-128064.pdf.
Here we demonstrate how to display "Seeedstudio" on the screen.
- Plug the Grove - OLED Display 128*64 onto the I2C port on Grove - Base Shield, and then plug the Base Shield onto Arduino;
- Download the library File:OLED_Display128X64 Library;
- Unzip it into the libraries file of Arduino IDE by the path: ..\arduino-1.0\libraries.
- Open the code directly by the path: File -> Example ->OLED_Display12864->OLED_Bitmap_Inverse_Display.
