 TODO und weitere Gedanken:
 - Anschlussplan wird nicht auf die Platine passen, aber kann man in den Deckel kleben.
 
+- Netzklasse für UBS passend machen, z.B. 0.8mm wide with 0.15 mm space. Impedance should be 90R.
+
 - Testpunkte - auch für Bauteile, die man von der Vorderseite schlecht messen kann.
-- Hardware Design PDF vom RP2040 anschauen
 - Bilder aktualisieren
 
-- OLED als Board kaufen oder irgendwie anders auf eigene Platine?
+- OLED als Board kaufen oder irgendwie anders auf eigene Platine? -> Nicht gut ohne Breakout kaufbar und Breakout hat noch diverse Kondensatoren und so. Ich würd's
+  einfach von unten an mein PCB löten.
 
 - Display-Board:
   - OLED mit SSD1306
