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!\u003cbr\u003e\u003cbr\u003eThe driver chip, SSD1306 can communicate in two ways: I2C or SPI. The OLED itself require a 3.3V power supply and 3.3V logic levels for communication, but the board includes a 3.3V regulator and all pins are fully level shifted so you can use with 3V \u003cem\u003eor \u003c\/em\u003e5V devices!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdafruit have updated the design to add auto-reset circuitry \u003c\/strong\u003eso that the reset pin is optional. \u003cstrong\u003eThe default interface is now I2C not SPI\u003c\/strong\u003e - since it speaks I2C you can easily connect it up with just two wires (plus power and ground!).  They've even included \u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSparkFun qwiic\u003c\/a\u003e compatible\u003cstrong\u003e \u003ca target=\"_blank\" rel=\"noopener noreferrer\" href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\"\u003eSTEMMA QT\u003c\/a\u003e\u003c\/strong\u003e connectors for the I2C bus so \u003cstrong\u003eyou don't even need to solder!\u003c\/strong\u003e \u003c\/p\u003e\n\u003cp\u003eThe power requirements depend a little on how much of the display is lit but on average the display uses about 40mA 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.\u003cbr\u003e\u003cbr\u003e\u003ca href=\"http:\/\/learn.adafruit.com\/monochrome-oled-breakouts\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eAdafruit have a detailed tutorial and example code for Arduino and Python\/CircuitPython\u003c\/a\u003e for text and graphics. You'll need a microcontroller with more than 1K of RAM since the display must be buffered. The library can print text, bitmaps, pixels, rectangles, circles and lines. It uses 1K of RAM since it needs to buffer the entire display but its very fast! The code is simple to adapt to any other microcontroller.\u003c\/p\u003e\n\u003cp\u003ePlease note that OLED displays are made of hundreds of...OLEDs! That means each pixel is a little organic LED, and if its kept on for over 1000 hours it'll start to dim. If you want to keep the display uniformly bright, please turn off the display (set the pixels off) when it isn't needed to keep them from dimming.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eRevision History:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of Nov 20, 2019\u003c\/strong\u003e Adafruit have done a re-design to make the display more plug and play.There is now an auto-reset circuit so that it will reset the display on power up. They've also changed the default protocol to be I2C instead of SPI. To convert to SPI mode you will need to cut two jumpers. They have also added two STEMMA QT \/ Qwiic connectors for plug and play usage! The board size, mounting holes and layout has changed slightly to accomodate these changes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBreakout Board Dimensions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePCB: 35mm x 35mm x 5mm \/ 1.4\" x 1.4\" x 0.2\"\u003c\/li\u003e\n\u003cli\u003eMounting Hole Dimensions: 29.5mm x 29mm \/ 1.16\" x 1.14\"\u003c\/li\u003e\n\u003cli\u003eMounting Hole Diameter: 2.5mm \/ 0.1\"\u003c\/li\u003e\n\u003cli\u003eScreen: 23mm x 35mm \/ 0.9\" x 1.4\"\u003c\/li\u003e\n\u003cli\u003eWeight: 6.2g\u003c\/li\u003e\n\u003cli\u003eThis board\/chip uses I2C 7-bit address between 0x3C-0x3D, selectable with jumpers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eOLED Display Details:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDiagonal Screen Size：1.30\"\u003c\/li\u003e\n\u003cli\u003eNumber of Pixels：128 × 64\u003c\/li\u003e\n\u003cli\u003eColor Depth：Monochrome (White)\u003c\/li\u003e\n\u003cli\u003eModule Construction：COG\u003c\/li\u003e\n\u003cli\u003eModule Size (mm)：34.50 x 35.00\u003c\/li\u003e\n\u003cli\u003ePanel Size (mm)：34.50 x 23.00 x 1.45\u003c\/li\u003e\n\u003cli\u003eActive Area (mm)：29.420 x 14.70\u003c\/li\u003e\n\u003cli\u003ePixel Pitch (mm)：0.23 x 0.23\u003c\/li\u003e\n\u003cli\u003ePixel Size (mm)：0.21 x 0.21\u003c\/li\u003e\n\u003cli\u003eWeight (g)：2.18\u003c\/li\u003e\n\u003cli\u003eDuty：1\/64\u003c\/li\u003e\n\u003cli\u003eBrightness ( cd\/m2)：100 (Typ) @ 12V\u003c\/li\u003e\n\u003cli\u003eDisplay 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.
