    spektrum trainer port pinout - VBAT ?

    hello

    Just finished my spektrum frsky module and now i want more and get the battery power from trainer plug.

    Searched a lot even in rcgroups but could not find if we can have power on the trainer plug (internal battery voltage).

    Any one knows how we can do that?

    thanks in advance.

    Not possible. JR/Spektrum systems have a 2-wire trainer port: ground, and ppm. There is no battery power available from the trainer jack like there is with futabas.

    edit:

    If you really wanted to void warranties you could probably replace the mono 1/8" jack with a stereo one, and use the additional pin for power. It all depends whether you want to modify the radio to get power.
    Far better is it to dare mighty things, even though checkered by failure; than to take rank with those who neither enjoy much or suffer much, because they live in the gray twilight that knows not victory nor defeat.

    thank you. it makes sense since the ground part of the plug would short other terminals if they were there.

    In theory you could do it w/ the stereo jack and a custom stereo cable to your module - but yes, if you inadvertently used a standard mono trainer cord it would short the two sleeve terminals together.
