Hi!
I'm new to the Feather community & would like some info, please.
Is it possible to 'network' multiple Feather boards together using their USB connectors? Sort of like a single master, multiple slaves....
I've dug around & it looks like the only thing the USB connector can be used for is uploading sketches & debugging.
I don't have the option of using Wi-Fi or LoRa.
Thanks in advance for any help!

Re: communicate with several Feathers using USB
Could I use the 4 port USB hub, #3298 or #4115, to connect multiple Feather boards?
The documentation says these are for a Raspberry PI, but could they be used for Feathers? It looks like there is a USB up-stream port to connect to another device.....

yep! you can do that, then use PySerial python on a computer to connect to each serial port, none of this is super easy but its possible to get them to communicate thru the computer :)

Re: communicate with several Feathers using USB
Or could I use wires....?
If I plug in an Ethernet wing to each Feather M0, I could wire them up on the same network, with different IP addresses.
The only thing there is I still need some kind of "hub", just like the USB 4-port hub if using the USB connections.
I'm curious, though. Is the USB connection on the Feather M0 capable of RS422 or RS485 communication? The schematic shows the micro-USB connection is tied to 'D+' & 'D-', which go to the SERCOM3 pins.... The datasheet says the USART is capable of full-duplex operation....
Thanks in advance for any help!!
