Hi,

I want to use the board on top of a ''motherboad'', so I need STM32 VL Discovery layout (or just P1, P2 and P3 layout dimensions), where can I find it? thanks in advance.

    Pretty sure you'll find it's all set up with a 0.1'' pitch in both X/Y so you can stick it on a proto/vero board. Would be easy to verify.

    Yes, it is

    ''so you can stick it on a proto/vero board.''

     

     

    Yes, you can

    The only question is: what to do about that pesky row of pins along the bottom?!

    Here's what I did:

    We are using the long protoboards from dipmicro.com with strip sockets.  The boards are high quality, plated through FR4 with solder mask.

    Because they are designed for SMT DIPS with 0.05'' spacing, the outer set of contacts are separate from the inner sets, so you can use 0.1'' parts under the Discovery board without conflict.

    You can handle the end contacts most easily by not installing a socket strip, but it was just a minute or two of effort to cut the traces between holes at the end.

    Always preferred pad-per-hole wire-wrap my self.

    Yes, that's the board -- the PCB-PB4.

    We put the strip sockets on column B and column N.  The puts a connected hole on the outside and the inside.  I find that the result is much neater and more reliable than an array of isolated holes, where you bend the wire over or bridge with solder to make contact.

    One advantage of a ''pad-per-hole'' board is when you have both ''horizontal'' & ''vertical'' rows of pins - as on the Discovery board...
