I am looking for a CAD drawing of the expansion board 3.0 as well in order to design an enclosure. Anything available? I can measure it myself, but it would be nice to reference the actual dimensions.
@VladimirAkopyan
there are a couple of expansion boards already which I think are enough for prototyping and even smaller units
PySense
PyTrack
Given the pricing and the fact that the grove connectors while nice to have are not essential whats the value add?
You can also use grove with pycom base boards you just need the grove to pin adapter
The only thing left is a solar trickle charger but these shouldnt be too hard to get
I think i know where you are coming from but just dont think there is an urgent need - maybe there is
