OLED I2C 0.96Inch 128x64px Blue Display


OLED (Organic Light-Emitting Diode) is a self-light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. In contrast to LCD technology, OLED does not require a backlight. OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays.

This OLED display is made of 128×64 individual blue OLED pixels. As each of these pixel emits light on its own, it doesn’t need a backlight panel like the classics 2×16 LCD display. Also because of this characteristic, OLED display can produce high contrast texts/images and it’s easily readable even under bright light. It can really display tons fo information despite the compact size.

This OLED display uses SSD1306 driver chip and can be controlled via I2C interface. Although there’s a 3.3V LDO (Low Dropout) voltage regulator built in this OLED module, SDA & SCL lines are not protected/level-shifted in any way. Hence we recommend using 3.3V only for this OLED display. Use 5V for supply and logic level at your own risk. Otherwise, you may use any logic level converter on the IO pins for that extra safety.

The I2C address for this OLED display is 0x3C, NOT 0x78 or 0x7A as printed on the back of the OLED board. Please remember to modify the address in your code to 0x3C in order to communicate with it. This I2C address can be modified in order to interface two OLED displays by using one host device. You just need to desolder the resistor near label ‘0x78’ and solder it back to the two pads nearest to label ‘0x7A’ as shown below. By doing this, the I2C address of the OLED display will become 0x3D.

I2C Address: 0x3C or 0x3D

Warning! This modification is not recommended for beginners who have just learnt how to solder as it involves SMD components and if the board is overheated, you may damage the OLED panel permanently.
