Dear Russell.You'd better use Grove universal 4pin cable,because they'll all be used most of the time,and sometimes only 3 pins are needed, and jst 3 cables will be enough.

Thank you for your response. I will need to access seeduino via Web (using Wifi Shield) to get and set values to sensors and LEDs via HTTP (may I use REST or similar as I do with my Flyport? Wiki information is not enough for me at this point:

It's compatible.

Hi, from the layout of the SainSmart Duemilanove we can see that all the pins are same as what it has on Arduino Duemilanove. So it is compatible.

Now the version of base shield is v1.2.Although v1.2 has shut down,but we have some in store.We would sell the new one after the older one sold out.

Hi,may it brings a V1.2 Base Shield with it.

Hi there, you can select arduino uno and download the code. thanks.
