With DC motors, it is common to put a freewheel diode and/or a capacitor in order to protect the equipment as the motor can induce current into the system.

I plan to use this board to control a 24V DC motor with a Arduino-like microcontroler. In an example in their documentation, they don't put such protection, so I wanted to know if it's unsafe, or is it that the board already protects the system?

The example in question: Example

    $\begingroup$ I agree this is a great question for Electrical Engineering. But I disagree that it is off-topic here, since it seems to fall under the very first bullet-point in "What topics can I ask about here?". $\endgroup$ – David Cary Feb 9 '16 at 14:44

    $\begingroup$ I agree with @DavidCarey - If a question about motor drive circuitry doesn't belong here then I don't know what does. Granted EE can answer (and already have, which is why I'm not voting to re-open) but the same can be said of basically any question that could be asked here. $\endgroup$ – Chuck Feb 10 '16 at 1:32
