STM32F401开发板

中文
这是一个基于开源作者hdpadi的作品"STM32F401RCDEV"进行改进和创新的工程。目前，这个工程CH340C版本已经验证。

对原作的设计变更主要包括以下几点：
1. 新增typec pd0触发功能, 使用5.1k电阻触发5V输出使得5VPD电源适配器可以为其供电

2. 替换了晶振型号, 重新规划了引脚走线与GND网络过孔增强了美观与信号完整性.

3. 替换了部分电源电容型号, 增强了电源稳定性.

因此，我非常欢迎和期待开源社区的成员们提出宝贵的意见和建议。如果您对这个工程有任何想法或疑问，请随时与我联系。
感谢您的关注和支持！让我们一起努力，推动开源硬件的发展和创新！

Dear Open Source Community Members,
I am sharing an improved and innovative project based on the work of open source author hdpadi. Currently, this project is still in alpha, so there may be some unknown issues.
The main changes in my design include the following points:
1. Added Type-C PD0 trigger function, using a 5.1k resistor to trigger a 5V output, allowing a 5V PD power adapter to power it.

2. Replaced the crystal oscillator model, replanned the pin routing and GND network vias to enhance aesthetics and signal integrity.

3. Replaced some power capacitor models to enhance power supply stability.

However, there may be potential problems and challenges. Therefore, I warmly welcome and look forward to valuable suggestions and advice from the open source community members. If you have any thoughts or questions about this project, please feel free to contact me.
Thank you for your attention and support! Let's work together to promote the development and innovation of open source hardware!
