Hm… the first time the configuration has not worked as intended, but I re-uploaded it and now, everything seems to work as expected.
Great work & thanks 
Now, only the i2c issue remains - and I hope, that the changes, someone provided on the github issue will work - then, all components are working for the Box3
[Update]
I really need to get used to the fact, that my Box3 Display is now turning off - when I am in front of the computer but does not move enough for the radar to recognize me
Bit strange, after weeks continuesly running display - and I always think, the device is crashing and rebooting lol
