## Pricing

- **Price:** $11.30 (inc GST) — $10.27 AUD, exc GST
- **Quantity discounts:** 10+ $9.86 (exc GST) · 25+ $9.55 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 2 today, and up to 50 more in 8–10 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SS102010551:1` (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/SS102010551:1.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)

## **How to Use**

The XIAO RA4M1 can be programmed using the Arduino IDE, making it accessible for both beginners and experienced developers. For CAN bus applications, pair it with a [Seeed Studio CAN-BUS Shield V2](https://core-electronics.com.au/can-bus-shield-v1-2-seeed-studio-43626.html) to create robust industrial communication systems. The board features stamp holes on both sides for efficient surface mounting in production environments.

Getting started is straightforward:

1. Install the Arduino IDE
2. Connect the board via USB Type-C
3. Select the appropriate board from the Arduino IDE board manager
4. Begin programming using familiar Arduino syntax
