wildfire stm32f103vet6 guide

I got a piece of stm32f103vet6, so I drew a development board. I wanted to be lazy, and followed the layout of Wildfire. After laying it out, I found that the flying wires were super messy┭┮﹏┭┮. I had no choice but to give up halfway, so after working hard, I finally finished it at noon today. Finished, but... I should go to Jialichuang to make a blackboard for such a tiring board. When I was almost finished, I found that the size exceeded ╥﹏╥ and I couldn't change it.

The original was a two-layer board, but now it has been changed to a four-layer board.

Differences from Wildfire official: miniUSB changed to microUSB

                                    RGB changed to 3 independent LEDs

                                    The ESP module is not onboard, it can be used directly.

 School hasn’t started yet, and some things are in school, so I can’t test Wildfire’s startup routine for the time being.
