Arduino UNO R4 Minima support?

Hello, I was wondering if the Uno R4 Minima was supported hardware. I am having trouble with the hardware setup process, but wondering if anyone has had any luck successfully interfacing matlab/simulink to this board.

Thanks

Hi @d mc,

Currently MATLAB Support Package for Arduino Hardware is not compatible with Uno R4 boards.

You can refer below links to know details of currently supported Arduino boards

Are there plans to support this?

Same inquiry here.

As of Nov 2024, it seems that R4 Wifi is listed on their webpage, however there is no assigned string, nor there is any mention of the board in the software itself when you actually try to connect it.

Btw, the new pre-release of R2025a does include both R4 Wifi and R4 Minima.

The support for the Arduino UNO R4 WiFi and the Arduino UNO R4 Minima boards starts from R2024b, as I learnt from the Release notes (see under section "Hardware support").

Important: I figured out, after some connection errors, that to connect the new Uno R4 Minima, the code line is not anymore just (in the example of the COM3 port used, on Windows)

a = arduino('COM3', 'Uno');

which fails, but

a = arduino('COM3', 'UnoR4Minima');

Or, if the board is genuine (Arduino-branded), simply this command does the job of recognizing port and board by itself:

a = arduino()

'Uno' tells Matlab that we are looking for an Uno up to R3, so it can't upload the firmware, since the microprocessor's architecture is different (AVR versus ARM).
