Linux image successfully installed on CB1 without any issues, connecting to the both 2.4 and 5GHz wifi APs.
Kiauh installed and KlipperScreen running. Bigtreetech HDMI touch screen works normally. I don't feel it is any slower then my Pi4 (2GB version), however I didn't connect printer MB nor camera yet.
What I find as annoying are the cables, will need to find both of them with an 90deg angle.
