I was looking at arduino nano boards here. Description says the arduino board is without welding plate. What does it mean for the user? If I buy this product will there be any issue? I understand that this board does not come with two headers soldered and I am OK with that.
Probably a mistranslation of soldering. As far as I can tell, it just means that the headers are not soldered on.
