Product Details
This protoshield allows you to add your own circuitry or components to your Grove system prototypes. This allows you access to 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.
