This blue color display is small, only about 1" in diameter, but very readable due to the high contrast of an OLED display. Perfect to display sensor readings, device status, etc. This display is made of 128x32 individual 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!
This breakout can be used with an I2C interface and the LCD can be controlled using 2 signal pins only. The board uses the popular SSD1306 Display Driver IC.

It's easier than ever to connect directly to your 3V or 5V microcontroller without needing any kind of level shifter!
