I was wondering what methods of breaking have been used with handyboard
motors.  Is it OK just to slam them in reverse for a few milliseconds ?
Or will the large current impulse be harmful to the motor and driver chips ?
It looks like the breaking mode of the motor driver chips, has been
disabled with a not gate that connects pins in1 and in2. (and the
same for in3 and in4) Would it be possible to disconnect the NOT gate
and use a digital output to get this extra feature ? I think the 4 modes
of the driver chips are

Pin        In1       In2
-------------------------
Neutral     0         0
Forward     1         0
Reverse     0         1
Breaking    1         1
