## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA1910:1` (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/ADA1910:1.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.)

- **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)

## Description

By popular request, you can now get Adafruit's 14-segment LED backpacks without the LEDs! These backpacks feature an HT16K33 I2C LED driver, they're simple and easy to use - you can use Adafruit's[ very nice library for the backpacks to get running in under half an hour, with numbers and letters displaying](https://github.com/adafruit/Adafruit-LED-Backpack-Library). If you've been eyeing matrix displays but hesitated because of the complexity, this is the solution you've been looking for!

Like Adafruit's other LED backpacks, these are end-to-end stackable and by soldering the address jumpers on the back you can have up to 8 backpacks all sharing the same two I2C wires!

Comes with a fully tested and assembled LED backpack & 4-pin header. Some light soldering is required to attach the header and, of course, the display.

**A set of two 2-digit 0.54" tall alphanumeric displays are not included,** [but can be purchased here!](https://core-electronics.com.au/search/?q=alphanumeric%20adafruit)
