## Restrictions

**For use in Australia**

- Operate only in bands and with settings that are permitted for your location and application. Check this product’s supported frequencies in the description/specs.
- If you intend to operate outside shared/licence‑exempt conditions (e.g. in other bands, at higher power, with high‑gain antennas, or extended duty cycles), you must have the appropriate authorisation.
 
**For use in other regions**

- Follow the spectrum rules for your country/region and select frequencies and settings accordingly.

A declaration of use will need to be submitted during checkout.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SS102110419:1` (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/SS102110419:1.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

Realtek RTL8720DN is a WiFi and Bluetooth module that has dual bands for WiFi communication. It is worth saying that this little module can support WiFi 5G and Bluetooth Low Energy 5.0 as well. This WiFi and Bluetooth module is a highly integrated WiFi and Bluetooth module with the main chip RTL8720DN, it can be regarded as an SoC for the WiFi and Bluetooth application with typical SBCs.

Except for the main chip, the Realtek8720DN module consists of a high-performance MCU named KM4, a low power MCU named KM0, WLAN (802.11 a/b/g/n) MAC, a 1T1R capable WLAN baseband, RF, Bluetooth, and peripherals. An inner antenna and many interfaces are available in this little WiFi and Bluetooth module.

**Features**

- WiFi and Bluetooth module.
- Support both WiFi 2.4G and WiFi 5G with protocol 802.11 a/b/g/n 1x1 from 20/40 MHz up to MCS7.
- Support WiFi low power mode.
- Support Bluetooth (BLE) 5.0.

**Peripheral Interfaces**

- 1 common ADC interface
- 2 log UART with standard baud rate support
- 1 I2C interfaces are shared with the PWM interfaces
- 1 SPI interfaces are shared with the PWM interfaces
- 4 PWM interfaces
- All of the above interfaces can be used as GPIO

**Applications**

- BLE beacon
- Industrial wireless control
- Bluetooth gateway
- Wearable electronic devices
