Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA5297:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description ## Description This OLED goes out to all the fans who want *more pixels in a smaller size*! Normally Adafruit's 128x64 OLEDs are the biggest ones Adafruit have stocked that can use I2C. This one is a whopping 128x128 pixels in crisp monochrome. This display is a petite 1.12" diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128x128 individual white 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; Adafruit really like these miniature displays for their crispness! The driver chip, SSD1107 can communicate in two ways: I2C or SPI. The OLED itself requires 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! If you are using I2C, Adafruit have included [SparkFun qwiic](https://core-electronics.com.au/catalogsearch/result/?q=qwiic) compatible **[STEMMA QT](https://learn.adafruit.com/introducing-adafruit-stemma-qt)** 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. [**QT Cable is not included**, but Adafruit have a variety in the shop](https://core-electronics.com.au/search/?q=stemma+qt+cable). This display, being 128x128 pixels, requires 128 \* 128 = 2KB of SRAM just to buffer the display. So **you can't use it with a small chip such as the Arduino UNO** (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. [Adafruit have both Arduino](https://github.com/adafruit/Adafruit_SH110x) and [CircuitPython support](https://github.com/adafruit/Adafruit_CircuitPython_DisplayIO_SH1107) for this display chipset (SH1107). Please note that OLED displays are made of hundreds of...OLEDs! That means each pixel is a little organic LED, and if it's 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. ## Technical Details **OLED Display Details:** - Diagonal Screen Size:1.12" - Number of Pixels:128 × 128 - Color Depth:Monochrome (White) - Module Construction:COG - Active Area (mm):20mm x 20mm - Pixel Size (mm):0.15 x 0.15 mm - Duty:1/64 - Brightness ( cd/m2): 100 (Typ) @ 12V - 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 ~35mA or so in practice but for precise numbers you must measure the current in your usage circuit.
