Monochrome 128x32 SPI OLED graphic display (ID: 661)
The Monochrome 128x32 SPI OLED has a crisp, high contrast display making it very readable even for its small size. This display is made of individual white OLED pixels, each one is turned on or off by the controller chip. The display makes its own light, no backlight is required, this reduces the power required to run.
The driver chip SSD1306, communicates via SPI only. 4 or 5 pins are required to communicate with the chip in the OLED display.
The OLED and driver require a 3.3V power supply and 3.3V logic levels for communication. A 3.3v regulator and level shifter has been added to the board! This makes it compatible with any 5V microcontroller, such as the Arduino. The power requirements depend 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!

- 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 ~15mA or so in practice but for precise numbers you must measure the current in your usage circuit.
