CH549L development board

Overview

I have nothing to do recently, so I designed a CH549L development board with the "as narrow as possible" width requirement.
This board can be plugged directly into the breadboard after soldering. It has on-board resettable fuse, USB protection diode, 5V to 3.3V LDO and 24MHz crystal oscillator, which has been verified to meet the minimum system requirements.

The finished product picture is as follows.
