In my application I use PWM1,2 for  diversion resistor (shunt regulator) and 
Power1,2 for protection (relay command).
In the future I plan to use PWM1, PWM2, and Power1 Power2 for a bridge in H.

I was looking to put dip switch. It is good idea, variable resistors may be 
used as a pullup or pulldown.

If I find space? I try to use the 4-5 buttons.

Now I have no reason. But you're right and thank you for the idea.

 For measuring frequency (rpm windmill, wind speed)

Is 75x85 mm, standard jaluino shield.
But exist in jaluino/shields an adaption for Arduino shields.
