It's work Thanks a lot

Sure, there is already the KiCAD file including everything to play around with on your own; added a picture of the schematic here for a quick glance without downloading.

Hey guys aside from these power-consumption issues, I am now running the Feather as gateway and node. And I get a strange problem. The gateway is attached to a raspberry pi via usb (by-id), which runs fhem. And everything works great for about an hour to 1 1/2. Then somehow the gateway stops receiving/communicating. I already tried an active USB-Hub incase the power consumption was too high for too long. But that didn't help. I have to reset the gateway and node to make it work again. Did anybody else ever experience similar behaviour?

BTW, I like how you both made a case for it. Very nice!
