CH340-ESP series fast programmer

Overview

Note:
It is an automatic download circuit that has not yet been verified
. Now the ch340 is expensive. You can't put one on every development board and work.

If it is reversed, it should not smoke. It
has a built-in output power switch to prevent it from being thrown into the device pile for testing. The pin is short-circuited (of course it needs to be covered with heat shrink tubing)
