    It creates problem on breadboard...it should be redesigned to all pins at one side..

    • littlefreak / about 11 years ago / 2

      I think it was designed to straddle the middle of a breadboard.

  • dave2 / about 16 years ago / 2

    Would be awesome if these were all pins along one end - the board is quite wide on the breadboards I have, and it's difficult to get access to the rows under it. (Would probably help with soldering this for newbies... like me :) )

    Would I be able to cut this and get the same functionality as http://www.sparkfun.com/products/716 at half the price?

    • aknewhope / about 13 years ago / 1

      this is for the jack that has magnetic(transformers) built in to protect the chip. This board works with the mag jack. The board you referred to works with a standard jack with no magnetic. As far as I know the pin out is spaced differently.

    I have been successfully using this with an mbed, but what are the 'gs1' and 'gs2' pins? My guess is they have something to do with a ground (shielded ground?) but the RJ45 works without those pins. Can anyone tell me what they are?

    • Kevin Vermeer / about 13 years ago / 1

      Yes, they are the shield over the connector. Connect them to ground. It's likely to work just fine 100% of the time without them, though.

  • fkmass / about 14 years ago / 1

    I have ordered some of these, but I received other circuit. What I received came with two sm leds, a couple of resistors and caps, and does not fit the magjack http://www.sparkfun.com/commerce/product_info.php?products_id=8534 pins. It only breaks Vcc, Gnd, Tx and Rx.
    Has anybody got one of these?

  • saccade / about 14 years ago / 1

    Ditto comment about pins along one side. Any hope for a new build of these?
