1 Your cable would be the determining factor, you can use either

3 Your extra unit could be a standard with no computer
3 questions
1) I'd like to connect a second unit to my V1 node using a USB hub. Do I use the USB-C on the side or the USB-A on the back?
2) Is there a limit to the number of units I can connect to a V1?
3) Whats the spec difference of the V1+2, because the V1 is running a on a pi - is the v2 also running on a pi?
Thanks!
