Mama Shield description:
The Mama Shield was designed for high-speed prototyping, and has 5 slots for inserting daughter-boards. Each slot has a 36 pins. The slots contains all of the Arduino pins plus 8 shared bus pins. The bus pins allow cards to communicate between each other.
The shield 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 are also a row of jumper pins with the jumpers in case you want to keep everything the same.
