I know I am sounding argumentative, but my question is where do you think your switch mode regulator or for that matter any electronic parts you plan to use are made. Grand Rapids, Minnesota???
There is no gray market involved. I ordered two boards, I screwed up the first board because my arthritic hands do not solder like they use to.
The board is so nice I ordered 5 more. In case someone local needs one. I will probably give them a board. For $1.15 I can be a spender
