Adafruit OLED Breakout Board – 18 bit Color 1.5 inch

• 1.5″ diagonal OLED, 16-bit color
• SPI interface
• 3.3-5V logic and power
• Dimensions: 43.17mm / 1.7″ x 42mm / 1.65″ x 5.42mm / 0.2″
• Display current draw is completely dependent on your usage: each OLED LED draws current when on so the more pixels you have lit, the more current is used. They tend to draw ~30mA or so in practice but for precise numbers you must measure the current in your usage circuit.
