    Hi,
    I am a bit confused, as it seems that there a different pin layouts of the MM shield.
    As in the thread/tutorial of @RacingMat, the pin layout looks like this:
    And this is also used by the original GitHub code of Sparkfun:

    But here is another layout:

    Hardware Pinout

    A0 : Enable pin for motor 1

    A1 : Enable pin for motor 2

    A2 : Current sensor for motor 1

    A3 : Current sensor for motor 2

    D7 : Clockwise (CW) for motor 1

    D8 : Counterclockwise (CCW) for motor 1

    D4 : Clockwise (CW) for motor 2

    D9 : Counterclockwise (CCW) for motor 2

    D5 : PWM for motor 1

    D6 : PWM for motor 2


    taken from
    http://www.instructables.com/id/Monster-Motor-Shield-VNH2SP30/


    Is this known or am I wrong ?
    How can I know, which layout my MM have ? (even if its a cheap China clone)

    cheers,

    I think it depends, if you want to use racingmat code or smc3 code, then the wiring diagram will be diferent

    Mmh, I thought again about it, and the code examples uses the same pins: 7 and 8 for Motor1, 4 and 9 for Motor2. It seems that only the description inside wiring picture from racingmat was not correct, as he said, that Pin 4 and 8 belongs to Motor1 and 7 and 9 for Motor2.
    I guess we can ignore this :)
