This is really nice - i think you should adopt 3 and 4 pin PH2.0 connectors in the same way as SeeedStudio has adopted grove connectors. If you placed them on some of your MCU boards, that would be really cool.
The fact that Grove is a weird connector causes problem all the time - PH2.0 can be crimped on any wire and is much better than pin array.
