Difference between the eu , us , jp versions

What is the main difference between the 3 versions of the devkit. Why is it important and are there any downsides using a us model in eu ?

The mini doesn’t come in region versions. The answer to the questions above would probably explain why

Hi there,

We write the efuse (wifi channels) for the azure sphere. so there are different versions. So the specific version uses in the related countries.

For the MT3620 development board, we leave it as default 00 and it can be used for all the countries. thanks.
