This is very exciting and I can’t wait for the day where everyone makes awesome gadgeteer modules. I have seen some by the community already and now I see it from a company.
I am waiting to see some code/schematics/samples to make sure those modules like the accelerometer/display will work on spider. This is what gadgeteer is about anyways.
Would it be worth having a section the wiki hardware pages for user based gadgeteer modules etc? After all the hard work Architect has gone to with his modules (awesome POE BTW) it would be a nice place to show case and maybe give others some inspiration?
A gadgeteer module should follow the specification for size, markings, type of connectors used, color of the board, etc. The specification is on gadgeteer site.
That driver that you have mentioned can be used to make a gadgeteer module.
