UNO Wifi R4 wrong amount of memory

Hi there,

I've got an Arduino UNO Wifi R4 and gave it a first try. When I compile the "Blink" example, the compile output displays:

Program size: 3236 bytes (used 10% of a 32256 byte maximum) (1.00 secs)
Minimum Memory Usage: 306 bytes (15% of a 2048 byte maximum)

In my opinion, the UNO R4 has:
- 256kB of Flash memory
- 32kb of SRAM
- an RA4M1 Mikro controller

What is going wrong here? Am I using the correct board with "Arduino Uno WiFi?

Thanks for your help in advance
Michael

Thanks for the report.

It appears from the log you have the wrong board selected in Visual Micro compared to the board in the image.

The UnoWifi is a separate board, from a separate board package, to the UnoR4WiFi.

If you install the "Arduino Uno R4 Boards" package in Micro Explorer > Board Manager, this will allow you to select the correct "Arduino R4 WiFi" board as described.

This will then show the correct amount of memory usage at the end of the compile.
