A bug indeed, I missed these Board subclasses when I changed from __init_subclass__ to __init__ in #96. I have made #103 to fix it.

The fact that it attempts to use the Unknown class means that the board you are on is not supported. If you want me to add support for it please open a board request issue, the template contains some commands to run that will give me the information I need.

Please use code fences when posting code or logs like so:

```log
