mating connector to the external I/O connector on ezDSPstkc5505

Brett Hancock

Greetings earthlings:

Can anyone suggest where I can get a mating connector (especially the non-PCB mountable version) for the ezDSPstkc5505 dev stick? Even if someone has a source for a ready made mating connector PCB or cable? I just want to be able to prototype some external connections without having to layout my own PCB.

thank you,

Brett H

    Hi,

    There is a matching connector available, but the layout has an error,. The alternative connector is hardly to get from the well-known sources. This issue has already been discussed here, maybe it is best if you try the search.

    Here you get the info from Spectrum Digital regarding the edge connector: http://support.spectrumdigital.com/boards/usbstk5505/revb/

    If you find a source for the alternative connector or any other connector that fits and is easy to get, please let us know :)

    Regards,

    i LOOKED AT THE REFERENCES. I WENT TO SAMTEC WEBSITE AND THE PRODUCT MEC1-130-02-S-D-NP-A DOES NOT EXIST.

    ALSO SEARCHED MOUSER FOR THE SAME PRODUCT NUMBER NO RESULTS.

    IS PCI EXPRESS THE ONLY ANSWER?

    I purchased a MEC1-130-02-S-D-NP-A connector from Samtec on 11/20/2009 ($8 plus shipping). the connector has 30 positions per side for a total of 60 positions. I tried this connector on the ezdsp USB Stick and the connector socket positions lined up with the card edge contact pins. This connector does not have a polarizer that would have interfered with mating to the circuit board. I searched for this connector on Google and got the Samtec website, where I searched for this part number.

    The site had this part number which directed me to their 1mm Mini Edge Card Socket MEC1 series. The part number derived from this page does not contain the same options. I would recommend that Samtec customer service be contacted to check that they can provide the connector without the polarizer.

    Samtec: www.samtec.com, call 1-800-Samtec-9 or www.samtec.com/call_us or Email: CustomerService@samtec.com

    Thanks

    I just ordered the connector.

    Don't know why i could not find it the first time.

    I had deliberately waited 2 months on ordering this part, waiting for the RevC version, to avoid this hassle. But sure enough, the part I got from Digi-Key was the infamous Rev B, and of course the associated polarized version of the connector does not fit/work. ARGG ! Precisely the kind of useless hassle I wanted to avoid. The key reason for getting the part and connector was to interface the I/Os to some of our other SPI/I2C/Analog sensors. So the questions I have are:

        (1) How well does the non-polarized connector work, since it is actually oversize. Is it stable or does it like to fall off ?

        (2) Is the connector useful in terms of interfacing to SPI/I2C/ADC/GPIO etc external I/Os or not ?

    At this point I am debating whether to bother with the hassle of ordering an odd-ball connector, or just tossing the ezDSP5505 into the junk barrel and looking at alternative competitor parts. The whole RevB board fiasco is a WOMBAT from my perspective, all because a Spec-D QA engineer couldn't spend 60 seconds to check if the spec'ed polarized connector worked. Any insights on the above 2 questions would be appreciated.

    Hi Wayne,

    I got the non-polarized connector as a sample from Samtec, but I don't use it - it is just too risky. Instead, I soldered the leads of a flat cable to the pins of the board and fitted another connector of my choice to the other end of the cable. I am using UART, SPI and GPIOs at the moment, that works well.

    Danny, if you have any better solution, please let us all know :-)

    Couldn't you just fill the gap (pins 37 and up in rev C board) with a piece of a pcb with the same width as the gap?
