       - Dann nehmen wir den.
       - Fun fact: Das untere Ende sind VSS-0.3V, d.h. mit dem hätte man sogar negative Ströme messen können.
     - Ich nehme mal Faktor 60, d.h. funktioniert bis 500 mA. Wenn man mehr will, muss man halt den Shunt tauschen.
+  - Wie viel Watt kann ich durch den Widerstand zum Strom messen schicken?
+    - Den 0R1 hatte ich schon größer gemacht, aber der ist harmlos wegen der niedrigen Spannung und bei Kurzschluss kann ich nicht viel machen (sofern die
+      Sicherung vor den 24V den nicht rechtzeitig abfängt).
+    - Die 2.4 kOhm für die 10 mA Messstrom sind aktuell ein 0402WGF2401TCE. Das WG heißt 1/16 Watt. Es fallen aber 240 mW ab. Upps.
+    - In dem Package wäre ok: 24/(1/16)×24 = 9.2 kOhm
+    - Das wären 2 mA. Das wären 16 counts am ADC. Nicht so toll. Aber selbst die 0805 haben nur 1/8 W.
+    - Dann wird's wohl ein Extended Part mit 1206.
+    - Oder auch nicht: Es gibt Basic Parts mit 2k und 4.7k. Wir machen das nicht dauerhaft an und der Motor hat auch noch 100 bis 500 Ohm. Ab 2.3 kOhm passt
+      die Power und wir machen das ja immer nur kurz an. Ich denke, 2k sind ok.
 
 
 
 TODO und weitere Gedanken:
 - Anschlussplan wird nicht auf die Platine passen, aber kann man in den Deckel kleben.
 
-- RC-Filter sinnvoll auslegen
 - Testpunkte
 
 - OLED als Board kaufen oder irgendwie anders auf eigene Platine?
