So there are internal voltage doublers and Charge pump circuitry which helps to obtain higher voltages from the supplied voltage. On the other hand the OLED display requires input voltage between 7V to 15V. with the help of a voltage regulator which converts input voltage between 1.8V and 6V to stable 3.3V output voltage. The Operating voltage of the SSD1306 driver is from 1.65V to 3.3V. Power supply requirements for SSD1306 OLED display module
#Ssd1306 arduino i2c example pdf
To know the detailed technical specifications read the official datasheet: SSD1306 Datasheet PDF for example we frequently find OLEDs with sizes 128×32, 128×64, with Blue color OLEDs, White color OLEDs and Dual Color OLEDs.
Since SSD1306 is versatile, manufacturing different color, size OLED displays are possible.
#Ssd1306 arduino i2c example drivers
There are many other drivers which has their own level of features. The OLED display which we are interfacing with Arduino in this article is integrated with SSD1306 Driver which is well known and powerful OLED CMOS controller. SPI communication is faster than I2C communication protocol but SPI requires more number of I/O pins for connection when compared with I2C which requires only 2 for data transfer and we can connect upto 128 devices, so its up to your requirement whether to opt for SPI or I2C.
Generally all the OLED displays for made for Arduino comes with driver packed in the module it self, they can be directly connected to the microcontroller, the driver with in the OLED display works as the communication system between the microcontroller board and the OLED display through I2C or SPI protocols. these sheets are placed between two conductors and emits light when electricity is applied to them. Yes, even I thought of any living organic matter, But later found that the OLED composed of sheet organic materials such as Coal. The Acronym of OLED is Organic Light Emitting Diode, You may get a doubt about organic.
