Using Propeller Project Board with QuickStart modules

Is there some trick to using QuickStart modules with a Propeller Project Board? I just soldered a female 20x2 header to my Rev A Project Board and plugged in a Human Interface Board with a Propeller Memory Card plugged into it and it doesn't seem to work. The same HIB+PMC works when plugged into a QuickStart board. Is there some jumper I have to use to enable the QuickStart header on the Project Board? Also, I assume that the QuickStart module should be plugged in so that it overlaps the Project Board like it does the QuickStart board, right? It isn't supposed to hang off the side is it?

    It looks like the module should stick out from the side of the project board. Look to see where pin 0 is on each header. Oh, you probably don't have a label on your QuickStart? I/O P0 is next to the silkscreen "1" on the USB side of the QS board.

    I just realized that myself. It would be nice if the boards were labeled so you could tell how to plug them in. The HIB has no label at all that I can see and the Project Board is labeled differently than the QuickStart.

    Anyway, thanks for the information. I hope I didn't fry the Project Board, the HIB or the PMC by plugging it in backwards!

    I also wish the QS were better labelled.

    Did you power the HIB through the onboard jack? If you did I/O P0 could possibly be damaged. If you were powering the boards through USB on the Project and QS, I don't think there should be any damage done. At least not to each Prop board or the HIB. There is a chance the PMB could have been damaged.

    Plugging the HIB backward puts 5V on P0. This is the IO0/DI pin on the PMB. It also reverses the power to the memory chips (could be bad).

    Looks like everything is okay. I guess I was lucky. I still vote for a consistent labeling across all QuickStart compatible modules.
