## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09964:1` (comma-separated SKU:qty pairs) and share the link. 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/CE09964:1.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)

A bigger version of the classic SSD1306 display. With a larger screen size (and bigger pixels) this display makes anything you put on it really *pop*!

To get started with this display, use any SSD1306 library, we love [this Micropython library by PerfecXX](https://pypi.org/project/micropython-ssd1306-driver/).

### Features

- Uses the two-wire I2C protocol, allowing for daisy chaining other 3.3V I2C modules
- White on black display
- The onboard charge pump makes the pixels much brighter than expected
- No external components needed, [just wire up](https://core-electronics.com.au/prototyping/prototyping-wire.html) power, ground and I2C - perfect for [breadboarding](https://core-electronics.com.au/prototyping.html#category_61)!
