Reserve-my-adapter

The current generation C6 is directly available in the following shops, which is why a reservation is unnecessary at the moment. I.e. just order there directly:

The adapter C6

the Stick Edition

and the adapter v5

allow being used via USB, WIFI, Raspberry Pi (excluding the stick),
or Ethernet (USR-ES1 module NOT included!).
Comes with an eBUS plug but without a USB cable.

For Ethernet, an additional module is needed that is available separately, e.g. as option at Elecrow. Or see the links in the docs.
