arduino-nano official full version

The four corners of the official board are too annoying and sharp, so I made them rounded. The official interface is miniusb, which is
an antique. You probably don’t have that kind of data cable at home, it’s too old. I saw that some makers use typec, which is indeed high-end,
but typec is a little more expensive, so I chose microusb. Most of the data cables I have are also microusb, and
this interface is also very economical. Everything else is exactly the same as official. A friend of mine who makes small cars uses this board and everything works fine.
So you can use it with confidence. I also hide many through holes in the lower part of the chip, which can make your board cleaner and more beautiful.
I have presented all the information about the board in the pcb, so just look at whatever you need. In addition, for the convenience of everyone’s printing, I did not add any mark or
text, so you can just print it without worry.
