SKRat correct pinout?

Hello, just received my BIGTREETECH SKRat and trying to configure it. I'm confused with the pinout of some pins. I use klipper with firmware RatOS. The config file from RatOS contains only pins, and the instructions with Github others. For example, in the RatOS configs for the first extruder motor, the STEP output is PB10, but in the instructions it is PB8. Can you help me somehow and explain where the values are correct and where they are not? And maybe send the correct pinout for all outputs, since I already found a discrepancy between MISO and MOSI pins (in instruction MISO has PB15 pin and MOSI has PB14, in RatOS config and on the board MISO has PB14 pin and MOSI has PB15)

shows that ratos is correct. The step for E1 (motor 5) is PB10
