I simply meant that a plug-in Nano can be swapped on any of the little controller boards I have and have recommended to other folks; i.e. the boards themselves are not usually the issue. I rarely dabble with new stuff, preferring most times to work out of my stash/junk box when possible, so I don’t have experience with any of the newer, fancier, boards and features… so I must defer to you and your experience on that.
