STM32G474CE core board V2

Overview

The G474 core board, drawn in preparation for the power supply question of the 2020 TI Cup Provincial Competition, has HRTIM and can produce high-resolution PWM.

V2 onboard resources:

24MHz crystal oscillator
32768Hz crystal oscillator
IPS240*240 screen interface
SWD debugging interface
Micro-USB power supply ~~or pin header power supply~~
3.26V voltage reference (using TL431)
One reset button with TVS electrostatic protection
One user button with TVS electrostatic protection
~~5V input undervoltage protection~~
~~5V output overheating and short circuit protection~~

**Precautions:**

The input voltage should be around 5V ( the TL431 reference voltage is generated directly from the 5V input )
