STM32 Placement Rotation unclear #44

I have a Problem with the STM32.

Unbenannt In the Official Assembly Image above the stm32 is facing downwards.

hmfile_hash_0f62a7f9 Here is the official Pinout for the STM32 F405 LPFQ

image This is a Screenshot from the Cheap Focer 2 in KiCad. According to the PINs in KICAD and the STM32 Datasheet, the right placement would be a 90° rotation to the right. However, in the official Assembly instructions it's rotatet 180°. Can somebody help me what's the right placement? Thank's in advance, Niklas

Could figure it out myself. The inscription official PINout Diagram for the STM32F40xx is 90° turned, so you can't use this for orientation. Instead take a look at this:

Use the little dot as a reference point.
