    Hello,

    I must say they are not friendly.
    They are talking about the latching circuit not telling what it is.(just to buy their pcb).
    Without this info it is not clear how it works.

    Greetings,
    Bertus

    It is a bug and is illegal in the USA. I don't think this forum should help in the endeavor.
