Arduino Nano Matter board specifications and price announced

The Arduino Nano Matter is the product of a collaboration between Arduino and Silicon Labs. The Nano Matter board was announced in January and is powered by SiLabs’ MGM240S chip. It offers multiple wireless connectivity options such as Matter, OpenThread, and Bluetooth Low Energy.

Support for the Matter standard is the Nano Matter board’s key offering. Matter is an open-source, connectivity protocol that lets smart home devices from different manufacturers interoperate seamlessly. The 45mm x 18mm board leverages dual-mode connectivity, with IEEE 802.15.4 (Thread) for mesh networking and Bluetooth Low Energy for short-range communication.

It is targeted at the Internet of Things, home automation, professional automation, environmental monitoring, and climate control applications. Prospective industrial applications include machine-to-machine interoperability, machine status monitoring, and worker status optimization.

The Nano Matter board can be programmed both online and offline, using Arduino IDE, Arduino CLI, and the Cloud Editor. The Silicon Labs core in the Arduino IDE comes with code samples for creating different Matter-enabled IoT devices.

A user manual for the Nano Matter is available on the Arduino Docs website, complete with a first-use tutorial, instructions on loading samples and working with different platforms, and guides on enabling the different modes of communication supported by the board. You can read more about the board’s specifications and find more detailed information in the documentation.

While it is currently priced at $25, the Nano Matter board isn’t available for purchase yet and the product page only shows a community preview, with a link to subscribe to the waiting list.

Some wasted potential, I’d say.
The onboard ATSAMD11D14 is used for SWD debugging the main microcontroller, which is pretty standard.
But what’s also standard for development boards is to have at least one serial port connected from the debug micro to the main micro, which is missing here.
Also not uncommon is to have additional functions, like measuring the power going into the main micro (which would make a lot of sense, since it’s a wireless IOT device), integrated logic analyzer, additional interfaces like I2C, etc.

Can you point me toward a board that has those extra debug and characterization features? I know Nordic has a pretty extensive feature set on their dev boards but IIRC they have a separate product for power profiling. Most everything else I’ve seen is just SWD and a UART if you’re lucky, but an embedded logic/bus analyzer sounds great.

Some of the Microchip boards have that (even the cheap ones), they call it the Data Gateway Interface (DGI), and there’s a special tool to viszualize the data:

The onboard debuggers also usually show up as a virtual USB drive, where you can just dump the hex file to have it written to the target MCU.

In comparison, the Arduino onboard debuggers look pretty outdated.

p.s. The data visualizer is already integrated into the MPLAB-X IDE (as a plugin). It can also perform power monitoring, if the board/debugger supports it.

Do you program it in Arduino C++ ? I dont like linux neither python, I wouldnt buy it if is not programmable in Arduino C++

Jean-Luc Aufranc (CNXSoft)

Yes, the board is programmable with the Arduino IDE. Linux would not be supported on this microcontroller. MicroPython might, but they’ve not mentioned it.
