Albert blogged about his mini pro shield project:
Just finished my little mini pro shield which makes it a little easier to use the mini pro with projects and it now also makes the mini pro easier to use with test and trial projects.
The shield has a 3.3V and 5v power supply on board with power rails so every sensor can be used
If any of you guys want those board . I shared the board on OSH park here.
It works like a charm
