    Which is the positive wire in this picture? Red or black? Red (or any other color except white, grey or green) is normally hot, white is neutral and green is ground. The connector from the adaptor has a + and -. I want to make sure I don’t burn my board up.

    The board is labeled if you are not confident, and testing the power supply with a multi-meter is always good practice. I use red as positive in that picture.
