SD Card Connector

autodeskguest

I need to use a Hinged Micro SD Card Connector with a card-detect (CD)

switch.  A suitable part is the Hirose DM3CS-SF and I have managed to find

an Eagle part for this (see attachment).  However, in common with a few

other Eagle parts for SD Card holders with CD switches, there are no

connections for the CD switch or the ground on the schematic symbol.  All

the pads are visible in the board component.  I realise that I can edit the

part as necessary but I wonder why the part is not complete and whether

there is something I am not realising?

Thanks for any assistance,

paradigm

    Hi Alan

    Maybe most people dont use the hardware card detect, chosing to use the

    signal on the card pin, anyway simply  add the pins 9 thru 13 to the symbol

    and connect them in the device

    10 is the card detect pin as I see it. Name the others ground with the @

    convention (See HELP - PIN)

  • Thanks for your assistance Warren.

    I think I have managed to amend the Library part to include the CD switch

    contact together with the four ground connections (using the GND@ notation

    as you suggested - very useful!).  It was not too clear from the datasheet

    which pad was the CD switch.  Only this morning I received some samples and

    could see that the CD switch contact is in fact on pad 11.  Pads 9, 10, 12

    and 13 are the GND connections.  Although it still needs to be verified I

    have attached the complete amended Library part in case anyone wants to

    look at it.  I should have given it a different name but was not confident

    in how to do this with the various component parts.  The Hirose DM3CS-SF is

    the only micro SD card holder I can find with a CD switch and it looks to

    be an impressively high quality item.
