Here you can register for a collective order of an eBUS adapter.
The new generation C6 will soon be available in the following shop, which is why a reservation is unnecessary at the moment. I.e. just order there directly:
eBUS Adapter Shield C6 at Elecrow
An enclosure is available there as well as option.
The adapter C6
and the adapter v5
allow being used via USB, WIFI, Raspberry Pi,
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 NOT included, see the docs for details where to get it
