Shield Dock
The Shield Dock is a super versatile prototyping shield. The Sheild Dock can be used in many different ways. Think of it as the multi-tool for your Arduino projects.
It can be used with a traditionally shaped Arduino, as a prototyping shield.
As a pin break-out for your other shields to a breadboard, or built into a permanent project.
Dock a Sippino, and you get the same power as a traditional Arduino at half the cost.
There are a variety of ways to put the Shield Dock into action, more info & complete kit description here.
