Hello, i'm making some progress; received the components this week.
Unfortunately it doesn't work... yet
For now i have SanityCheck failure in to logs.
I'm afraid my soldering of all these little components is not good. I tested with a multimeter the 4 pins and i have continuity on one of them but maybe not the others so i guess i will have to try remelting all these small regulators ???
As previously noted, Sensebender Gateway sketch from 2.3.2 with MySensors SAMD Boards 1.0.6 does not compile with Arduino SAMD Boards 1.8.9. Rolling back to Arduino SAMD Boards 1.8.8 or earlier version works.
