**Type:** Product page · **SKU:** ABX00143 · **Brand:** [Arduino](https://core-electronics.com.au/brands/arduino-australia) · **GTIN:** 7630049205406
**Page:** https://core-electronics.com.au/arduino-nano-r4-with-headers.html ([markdown](https://core-electronics.com.au/arduino-nano-r4-with-headers.html.md))

The Arduino Nano R4 with headers brings the robust performance of the RA4M1 microcontroller into the beloved Nano form factor, offering a compact, ready-to-use solution for embedded development, creative prototyping, and educational projects.

## Pricing

- **Price:** $23.95 (inc GST) — $21.77 AUD, exc GST
- **Quantity discounts:** 25+ $20.68 (exc GST) · 100+ $19.60 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 18 today; more stock is typically available with a 10–14 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ABX00143:1` (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/ABX00143:1.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

Small but capable, the Arduino Nano R4 with headers packs the Renesas RA4M1 (Arm Cortex-M4) into a tiny 45 x 18 mm board that is ready for breadboards and rapid prototyping.

Use it to make compact projects, connect Qwiic sensors for quick I2C expansion, or embed the board directly into custom PCBs for space-constrained products.
