    I will be installing the male headers on the PB16 and the female headers on the PB just so it matches the F8-PBs I have. In case I need to swap PBs.

    I think Scott would have laid it out that way simply because all sockets are female on the board side. I don't think there are any benefits to doing it either way for the PB except for consistency.

    I did point this out to Scott a while ago. He likely needs new pictures. Next time one of you solder a board, if you could you snap a few pictures to send off to him maybe he can get the docs updated.

    Basically, it is generally recommended to put the FEMALE headers onto the PocketBeagle as that matches some of the other boards out there. That includes the PocketBeagle based boards from me, but also some of the things like USB hubs and such available from Tindie and other boards. It's also a bit safer for the PB. If the PB is off the board and sitting on a desk plugged into the computer via USB, male pins on the bottom would short out a lot easier and damage things.

    In the instructions I do say put the headers on the PCB and the pins on the PB. I did this so I wouldn't stab myself with sharp pins while soldering all the other components. It has been pointed out to me, that this is opposite of all other BBB and PB caps. With my configuration it easier to short the pins on the PB when running the PB not attached to a cap and damaging it. I plan on updating the PDF to swap the header and pins, I just don't have any picture with the pins on the PCB side.

    For myself this is not an issue as I don't plan on using the PB for anything outside of the controller.
    I would just leave it in the controller when doing anything with the PB.
    But I do see the logic in having the female on the PB as pointed out by Dan if I were to use the PB for anything else.

    Thanks guys, those explanations make a lot of sense. I've toyed with Arduinos and various PIs, but never the Beagles...

    I updated the PDF manual with some Kicad 3d renders to illustrate the pin headers on the PCB.

    Finally got my boards in yesterday. Just can't seem to upload an image of them!

    Size of the scan usually gets me. The image size supported on the board is pretty small.
