Grove - OLED Display 0.96 inch


Grove - OLED Display 0.96” 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.


  • Grove compatible interface
  • Communicate Mode:I2C
  • Low power consumption
  • Display Color: White
  • Wide range of operating temperature:-20℃~70℃


Please notice: heavy impact or stress on the OLED will cause the breakdown of screen.

Getting Started

With Arduino

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 SSD1308_1.0.pdf and LY190-128064.pdf.

Here we demonstrate how to display “Hello World” 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 or Seeeduino;

  • Download the library code from GitHub;

  • Download and upload the code. If you do not know how to upload an Arduino sketch, please visit for Windows user or for Mac user. You can see the result as below.

Tips: if you use Seeeduino, please also select Boards under Tools as you upload sketches.

With Beaglebone Green

To begin editing programs that live on BBG, you can use the Cloud9 IDE. As a simple exercise to become familiar with Cloud9 IDE, creating a simple application to blink one of the 4 user programmable LEDs on the BeagleBone is a good start. If this is your first time to use Cloud9 IDE, please follow this link.

Step1: Click the “+” in the top-right to create a new file.

Step2:Copy and paste the following code into the new tab

from Adafruit_I2C import Adafruit_I2C
import time
import math

Oled = Adafruit_I2C(0x3c)

grayH= 0xF0
grayL= 0x0F

BasicFont = [[0 for x in xrange(8)] for x in xrange(10)]

def oled_init():
    sendCommand(0xFD) # Unlock OLED driver IC MCU interface from entering command. i.e: Accept commands

    sendCommand(0x75)    # Set Row Address 
    sendCommand(0x00)    # Start 0
    sendCommand(0x5f)    # End 95 

    # Column Address
    sendCommand(0x15)    # Set Column Address 
    sendCommand(0x08)    # Start from 8th Column of driver IC. This is 0th Column for OLED 
    sendCommand(0x37)    # End at  (8 + 47)th column. Each Column has 2 pixels(segments)

    # Init gray level for text. Default:Brightest White
    grayH= 0xF0
    grayL= 0x0F

        C=' '

    for i in range(0,8,2):
        for j in range(0,8):
            if bit1:
            if bit2:

def oled_putString(String):
    for i in range(len(String)):

if __name__=="__main__":
    print 'hello world'

Step3: Save the file by clicking the disk icon with with the .py extension.

Step4: Connect Grove - OLED to Grove I2C socket on BBG.

Step5: Run the code. You’ll find that the Grove - OLED outputs “Hello World”.


Help us make it better
