    So I noticed that the Carmadillo project uses an Arduino Motor Shield R3. Does anyone know if there is a special configuration needed for this? I've tried using the shield before and at start up it causes the motors to spin really fast until the Udoo completely boots up.

    Any suggestions or is this normal behavior?

    For other's reference: http://arduino.cc/en/Tutorial/DueMotorShieldDC

    I also suggest cutting the Vin jumper on the bottom of the board to prevent 12+ volts going to your motors.

    The only thing I haven't figured out yet is why it causes the motors to move as it boots up. I'm guessing all the pins go LOW during start up which means the motor brake is disabled.
