This is a basic 5V 16 character by 2 line OLED display with yellow text on a black background. OLEDs (Organic Light Emitting Diode) differ from LCDs in that they can produce their own light instead of requiring a backlight, this provides you with an advantage of lower power consumption and better viewing in the light!

This OLED screen utilizes the RS0010 chipset instead of the HD44780 chipset which means the pin out will be slightly different.  While you will need ~6 general I/O pins to interface to this screen. Check the documents section below for pin outs and driver library.
