Hello Everyone, this is my attempt at creating a board centered around the STM32F103C8T6 (used this MCU because the blue pill board is what I have available locally to test code) for a uni project. I study Computer Engineering and don't have the best background in electronics, so this was mostly made by copying stuff from Phil's Lab YT tutorials.

The routing is kind of shoddy, and I realized mid-design that I should have probably grouped the components and had them use GPIO pins on a specific side to make placement and routing easier, but I had already submitted the initial pin assignment to the professor and had to make it work, and this is what I came up with.

I have 2 questions mainly:

Since my intent was to power this board via USB, is this LDO setup functionally viable, and are there any thermal considerations that I should consider, or is this good enough?

The board is mainly to be used as a prototyping board for my own use.

2nd question is about component placement: are there any components that are out of place in a way that won't allow them to function properly? For example, for the accelerometer, in its datasheet it's mentioned that it should be placed close to a mounting point but right now its just placed randomly where I could route it.

This won't be used for anything with hard accuracy requirements or the such, I mainly just need the board to "work."

Any helpful comments are greatly appreciated.
