This display is made of 128x32 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe driver chip SSD1306, \u003c\/span\u003e\u003cstrong\u003ecommunicates via I2C only\u003c\/strong\u003e\u003cspan\u003e. 3 pins are required to communicate with the chip in the OLED display, two of which are I2C data\/clock pins.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe OLED and driver require a 3.3V power supply and 3.3V logic levels for communication. To make it easier for our customers to use, we've added a 3.3v regulator and level shifter on board! This makes it compatible with any 5V microcontroller, such as the Arduino.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe power requirements depend a little on how much of the display is lit but on average the display uses about 20mA from the 3.3V supply. Built into the OLED driver is a simple switch-cap charge pump that turns 3.3v-5v into a high voltage drive for the OLEDs, making it one of the easiest ways to get an OLED into your project!\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eOf course, we wouldn't leave you with a datasheet and a \"good luck\": \u003c\/span\u003e\u003ca href=\"http:\/\/learn.adafruit.com\/monochrome-oled-breakouts\"\u003eWe have a detailed tutorial\u003c\/a\u003e\u003cspan\u003e and \u003c\/span\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_SSD1306\"\u003eexample code in the form of an Arduino library\u003c\/a\u003e\u003cspan\u003e for text and graphics.
