ProtoShield is used in conjunction with Arduino Duemilanove.
Used to build a circuit prototype, can be directly soldered components on the board.
Can also be connected through the mini breadboard circuit.
1 reset button, 1 general use button, and 2 LED circuits can be used directly.
5V, GND, and Raw pins are exposed as well.
The mini breadboard has 170 tie points.
SOIC place for IC.
The breadboard sticks on the prototype shield with its self-adhesive backing
