## Pricing

- **Price:** $14.40 (inc GST) — $13.09 AUD, exc GST
- **Quantity discounts:** 10+ $12.70 (exc GST) · 50+ $12.44 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA458:1` (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/ADA458:1.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)

## Description

Make a scrolling sign, or a small video display with this 8x8 gridded bi-color LED matrix. Only 1.2" on a side, it is quite visible but not so large it wont plug into a breadboard! 128 LEDs are contained in the plastic body, 64 red 320mcd and 64 green, in an 8x8 matrix. Every grid has two LEDs inside so you can have it display red, green, yellow or with fast multiplexing any color in between. This display is bright, beautiful and funky with nice diffused square lenses for a striking look. There are 24 pins on the side, 12 on each, with 0.1" spacing so you can easily plug it into a breadboard with one row on each side for wiring it up.
 
 Since the display is in a grid, you'll need to 1:8 multiplex control it. We suggest either using two [74HC595s](https://core-electronics.com.au/74hc595-shift-register-3-pack.html) and [TPIC6B595](https://core-electronics.com.au/tpic6b595-high-power-shift-register-tpic6b595.html) (using the 74HC' to control the 16 anodes at once and then using the TPIC' to drive one cathode at a time) or using two [MAX7219](https://core-electronics.com.au/max7219cng-led-matrix-digit-display-driver-max7219.html) which will do the multiplexing work for you.
