# MAX7219 Serial Dot Matrix Display Module

**Type:** Product page · **SKU:** CE05175 · **Brand:** [Core Electronics](https://core-electronics.com.au/brands/core-electronics-australia)
**Page:** https://core-electronics.com.au/max7219-serial-dot-matrix-display-module.html ([markdown](https://core-electronics.com.au/max7219-serial-dot-matrix-display-module.html.md))

These modules can be mounted flush side-by-side to extend them far beyond the 8x8 matrix. For example, you could have a 8x32 matrix! At the core is a MAX7219 - a very well documented chip in the Arduino community (along with ever other flavour of micro controller).

## Pricing

- **Price:** $2.40 (inc GST) — $2.18 AUD, exc GST
- **Quantity discounts:** 6+ $2.07 (exc GST) · 20+ $1.98 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 25 and Aug 31.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE05175:1` (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/CE05175:1.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)
