## Pricing

- **Price:** $49.75 (inc GST) — $45.23 AUD, exc GST
- **Quantity discounts:** 10+ $43.42 (exc GST) · 25+ $42.06 (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=SS113030023:1` (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/SS113030023:1.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)

Ameba RTL8722DM mini Board (AMB 23) integrates the RTL8722DM SoC which is the latest generation SoC of the Ameba IoT solution family and it is powered by a high-performance 32-bit dual MCU with a new architecture from Arm®; an Arm®v8M (Cortex-M33 instruction set compatible) running at up to 200MHz and an Arm®v8M (Cortex-M23 instruction set compatible) running at up to 20MHz.

This SoC also integrates the latest high-security architecture (Trustzone-M Security) with ultra-low power consumption suitable for IoT (Internet of Things) applications. Besides the high-performance MCU, RTL8722DM SoC also integrates the latest wireless technologies such as dual-band Wi-Fi (2.4GHz/5GHz) and Bluetooth Low Energy (BLE5) mesh.

Ameba RTL8722DM mini Board (AMB 23) features rich I/O peripherals such as a high-speed SDIO and USB interface, audio codec, key-scan and touch key, LCD panel controller, embedded 4.5MB SRAM(512KB SRAM + 4MB PSRAM), and configurable GPIOs that can function as digital peripherals for various applications. Through these interfaces, AmebaD can connect with electronic components such as LED, switches, manometer, hygrometer, PM2.5 dust sensors, …etc. All-in-all Ameba RTL8722DM mini Board (AMB 23) is an easy-to-program platform for developing all kinds of IoT applications.

Ameba RTL8722DM\_MINI currently supports Windows XP/7/8/10 32-bits and 64-bits, Linux and Mac operating systems. Now, we can use Arduino IDE to develop applications on RTL8722DM\_MINI, and the examples of Arduino can run on RTL8722DM\_MINI too.

In addition to features found on the regular RTL8722DM, the new mini development board also reduces the size to better fit into your projects.
