The PCB used for the Mama Shield can also be assembled as a card with an Arduino socket, thus we have "Mama Shield Card".  This way you can stack about three Arduino shields on one Arduino. 

The Mama Shield Card also has a switchboard so you can easily reconfigure the pin mapping.
the switchboard can be used much like an old-style switchboard was used by a telephone operator to connect a call.
There is also a row of jumper pins with the jumpers in case you want to keep everything the same.

Switchboard pins:

Analog 0-5
Digital 2-13

Cuttable solder jumpers pins:

Digital 0-1
analog reference
voltage in

non-configurable pins:
