1. 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.

3. Specifications Items Min Norm Max Unit Power Voltage (VCC) 3.3 5.0 5.5 V Driver IC SSD1308Z - Display Color White - Dot Matrix 128×64 - Panel Size 26.7(W)×19.26(H) mm Active Area 21.74(W)×11.175 (H) mm Dot Pitch 0.17(W)×0.175 (H) mm Dot Size 0.15(W)×0.
4. Usage 4.1 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 consultFile:SSD1308_1.0.pdf and File:LY190-128064.pdf. Here we demonstrate how to display "Seeedstudio" on the screen.

You can open other examples in the same menu bar. The key code here is the main instruction program extracted by the example, hope it can be helpful for you to understand clearly. For more details, please check the Demo code Resources linked. Note:This module is similar to Grove - OLED Display 96*96 in its usage and some library functions, you can make an gray 128*64 image arbitrary that can be shown on OLED 128*64. Please consult the latter one's Usage part of WIKI page for detailed instructions. 4.
