Arduino NANO C port version

 I like Arduino and Jialichuang EDA very much, but I suffer from the fact that PCB proofing downloaded from the Arduino official website is not directly free in Jialichuang, and there is currently no version in the open source community that is as "elegant" as the official Arduino version. This board was drawn.
  In addition to the appearance of the design being basically similar to the original version (which I copied), the USB interface was changed to Type-C to solve a small pain point that the original version was not elegant enough;
  at the same time, through careful selection of materials, the appearance remains basically unchanged. The cost is compressed as much as possible, so that this product can be produced with a relatively small cost (30+) PCBA. It is really a must-have board for DIY enthusiasts to use their creativity when traveling at home.
