    Default MK3/4 SD card connections.

    Hello,

    Has anyone here successfully connected an Arduino SD car module to the Mk3/4? There's a thread over on planetCNC forum which shows how to do it with a Mk2, but it's advised the connections are different for the newer boards. It seems the main pin not clear is where the CS connects to on the board.

    Thanks

    Andy

    Mk3 series uses SD protocol. Mk2 series and Arduino use SPI protocol.
    SD protocol uses only 3 pins: DAT0, CLK and CMD. Just make sure that other data pins are not connected.
