A small, highly readable OLED display, a beautiful addition to any project!
Display is made up of 128x32 white OLED pixels
The display makes its own light so no backlight is required, which also gives the screen a lovely high contrast
The driver chip communicates via I2C only. 3-pins are required to communicate with the chip in the display, 2 of which are I2C data/clock pins
3.3.V regulator and level shifter included to make the screen compatible with any 5V controller
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!
Check out Adafruits tutorial and Arduino library for example code. You'll need a microcontroller with more than 512 bytes of RAM since the display must be buffered, but its very fast!
