PD input multi-functional power supply module [Verified]

Overview

This project has been tested and verified, and can be used with confidence.
===============================
Appearance

Design Summary:
Utilizing the CH224K decoy PD input, it supports 12V/20V input and can simultaneously output 20V/12V, 5V, and 3.3V, with a maximum output current of 3A for each. It can be used for centralized power supply of power devices (such as rotary motors), microcontrollers, sensors, and other equipment. Only a single Type-C data cable is needed for all power supply, reducing wiring complexity and improving design aesthetics.
Material selection and layout are based on the datasheet.

Charger requirements:
The charger must have at least 20V 3.25A output (generally a 65W PD charger). It does not currently support proprietary protocols such as Huawei's.

Usage:
Select 12V or 20V trigger voltage using a toggle switch. Whether using 12V or 20V, the 5V and 3.3V outputs will not be affected.

Why is it that when compiling, adding a component only requires #define INCLUDE_XXXX? Where are these components stored and how are they added to the kernel?
