Grove - Proto Shield for Arduino

Proto shield provides a way for you to connect with Arduino and Breadboard to fast build and verify your prototypes.
Grove - Proto Shield for Arduino allows you to add your own circuitry or components to your Grove system prototypes. You can access all four lines from the connector cable: S0, S1, VCC, and GND. There is also an extra normally-open button to take advantage of. The hole spacing makes using normal DIP-format ICs and other components very simple. You may wish to purchase more for future use in advance.
