Hey, I am a complet beginner when it comes to creating schematics and pcb. I also dont know if this is the right play to ask this question, cause I am also pretty new to writing Forum entries.
I have created following schematic for an STM32103 Microprozessor and dont know if I the whole project would work. Could someone have a look on it?

Hope you guys will help me out.
