This OLED is a whopping 128x128 pixels and it even has an extra bonus - it can do grayscale pixels! Yep, you get the same crispness of a monochome OLED but with 16 levels of grayscale.\u003c\/p\u003e\n\u003cp\u003eThis display is a petite 1.5\" diagonal , but very readable due to the high contrast of an OLED display. This display is made of 128x128 individual grayscale 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 these miniature displays for their crispness!\u003c\/p\u003e\n\u003cp\u003eThe driver chip, SSD1327 can communicate in two ways: I2C or SPI. The OLED itself require a 3.3V and 12V power supply and 3.3V logic levels for communication. Adafruit include a 3.3V regulator and 12V boost converter, and all pins are fully level shifted so you can use with 3V or 5V devices!\u003c\/p\u003e\n\u003cp\u003eIf you are using I2C, Adafruit have included \u003ca href=\"\/en-eu\/collections\/qwiic\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSparkFun qwiic\u003c\/a\u003e compatible \u003ca href=\"\/en-eu\/collections\/stemma-qt\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSTEMMA QT\u003c\/a\u003e connectors for the I2C bus so you don't even need to solder! Plug and play with any board that has a Qwiic or STEMMA QT connector for effortless prototyping and development.\u003c\/p\u003e\n\u003cp\u003eThis display, being 16-level (4-bit) grayscale and 128x128 requires 128 * 128 * 4 bits = 8KB of SRAM to buffer. So \u003cstrong\u003eyou can't use it with a small chip such as the Arduino UNO\u003c\/strong\u003e (ATmega328 or 32u4). Pick a microcontroller or microcomputer with 16KB+ RAM - a SAMD21, SAMD51, ESP, nRF52, Teensy, etc will do an excellent job. As long as you have I2C or SPI interface available, you're good to go - SPI will be much faster but I2C requires fewer pins.\u003c\/p\u003e\n\u003cp\u003eAdafruit have both \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_SSD1327\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eArduino\u003c\/a\u003e and \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_CircuitPython_SSD1327\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCircuitPython\u003c\/a\u003e support for this display.\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","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":32283036090451,"sku":"ADA4741","price":21.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/4741-07.jpg?v=1603287309","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-grayscale-1-5-128x128-oled-graphic-display-stemma-qt-qwiic","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
