    Hello to the group,

    I am looking for a way to get pc boards that will allow me to mount a
    40 pin micro, and still have some holes on either side of the pins to
    mount things like pulldown resistors, caps,etc.

    I have been using boards like the ones the ratshack sells. One rail on
    each side, middle is spaced for up to a 20 pin DIP and 4 or 5 holes on
    either side to mount other components to.

    For reference, the ratshack board is called "experimenter printed
    circuit board" and the part number is 276-170. Datak makes boards
    similar to it (and a little less expensive), but when you mount a 40
    pin DIP, there's not much room next to the pins to connect other

    I have been to the expresspcb site, and they sound like a good way to
    go, but they only do double sided boards (I am not sure what that
    means). All I need is to mount components to one side and solder them
    on the other, with through holes, similar the the ratshack boards but
    either with more through holes on either side of the pins, or larger
    spacing to accomodate a 40 pin dip socket.

    Any tips, tricks, links, or links appreciated.

    If you don't mind doing a little CAD work, there's a couple places
    that do inexpensive single sided boards, like olimex or futurelec.

    It's also not that hard to etch your own single sided boards.

    Depending on the micro, you might be able to buy a proto board for
    that specific micro, which includes some of the support logic you need
    for it.

    In addition to the Vector products that John Fields referenced (widely
    available; try Digikey &c) there are some useful, inexpensive layouts
    available at

    Thank you all. I used to use expresspcb to build my own board, but I
    guess I am looking for a ready made solution now. My boards never did
    come out that good.

    Anyway, thanks to all who replied, I will check out the links.

    You don't need those strips of holes, but if you do, you can jumper
    to them with a piece of wire on the solder side, i.e, simulate a
