Don't want to use a StickIt! Board? Fine, be that way! You can plug the StickIt!-Grove into a breadboard and connect whatever you want to your Grove modules.
Like everything we do, we made the entire StickIt!-Grove design open-source. All of it: schematic, PCB layout, documentation — everything!
Haven't you figured us out by now? We don't do the whole fancy box thing. All you get is the board and a few headers. That's it. It cuts down on shipping costs. And the manual is online.
Did you not see the link to the manual we just gave you? Anyway, it's four sockets on a board! How hard could it be?
