Hi Kevin!
Can you please let me know how you entered/imported the BC847
library/module for kicad? Is it something you did yourself or imported
from some public reference library?
error : pin 1 and 2 of BC847 are swapped
source : KiCAD way of doing footprint + wrong verification on my side
(must have used another NPN transistor or BC847 datasheet to check)
effect : the two BC847 NPN transistors are affected. the current flow in
the wrong direction
workaround : solder the BC847 upside down
in Kicad there is no footprint for BC847. the footprints are general.
I assigned the SOT23 footprint for BC847, but the footprint is only
about the pad size and position. It does not ensure the correct pin
assignment. I verified them wrong.
