 TODO und weitere Gedanken:
 
-- LDO für 3.3V ist nicht mehr verfügbar.
 - Subraum-Logos?
 - Rotation der Komponenten bei JLC checken und ggf anpassen
   https://github.com/INTI-CMNB/KiBot#notes-about-the-position-file
 - Bei den Dingen mit Offset bei JLC (Wannenstecker, Stiftleisten) ein eigenes Package machen, wenn ich nix besseres finde.
-- Eventuell noch Kontaktpunkte oder Stiftliste auf dem Display-Board, für wenn man noch was am I2C dran hängen will (im Gehäuse aber unabhängig von der Heizung).
 - sch.pdf Dateien manuell aktualisieren und im README verlinken.
 
 - Bekomme ich den KF250T doch in 3D? Angeblich kann KiBot das von EasyEDA laden (aber ggf nur für Blender)?
   https://github.com/INTI-CMNB/KiBot#lcscjlcpcbeasyeda-3d-models
