OLED Display

OLEDs we have in hackSpace are small displays; they are also known as monochrome displays, they are only about 1” diagonal, but very readable due to the high contrast. This display is made of 128x64 individual white OLED pixels, each one is turned on or off by the micro-controller. Because the display makes its own light, no backlight is required, allowing better energy saving. Briefly saying an OLED display is just better and modified version of and LCD display.

The driver chip SSD1306, communicates via I2C only. 4 pins are required to communicate with the chip in the OLED display, two of which are I2C data/clock pins (SCL and SDA). The OLED and driver require a least 3.3V power supply.
