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.
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 ???
I've modified the PCB and added support for the 5W module (you can select to use either the 3W or 5W on same PCB). I've also added screw holes. Here is the list of changes:
Imported to KiCad 5.1.8
Added M2.5 screw holes
Added EMI/EMC filter
Added HLK-5MXX 5W models
Board size: 72 mm * 42 mm
I've also changed track width to a more proper one for the respective voltages (secondary has larger current). You can leave out the EMI/EMC filter (add jump wires instead of the inductor) as it is not tested. I have not updated the BOM, but e.g. the inductor part id is mentioned in the circuit and the X2 cap is of common size.

Comments are appreciated. I'm new to KiCad, so I might have done some mistakes. The KiCad project should maybe have been named as it was originally, but I renamed it to keep it separate.
