Circuit Diagram for Friend Dev Kit V2

[Neotastisch]

Is your feature request related to a problem? Please describe.
It is quite hard to understand which ports need to be connected from a single picture and with no documentation

Describe the solution you'd like
A simple diagram for connecting the different parts. Even better would be a guide for inexperienced users

Additional context
PS: If I get a diagram I would be happy to make a guide for assembling it

Will there be a switch to turn it on and off? There are none listed in the parts list. Is that a mistake?
