WiFi remote boot does not occupy pcie direct plug-in fpanel

Overview

Use esp8266 as the main control because there are networking requirements.
Solid state relays are used as a compromise solution. This solution directly replaces the human action of pressing the button. It is simple, reliable, and has a low failure rate. The disadvantage is that it is too large. Directly using gpio control may reduce the PCB area by half. See detailed discussion below.
Since fpanel is not powered, we need a 5v power supply line, which is placed in the fool-proof position of fpanel (upper right corner).
Manual switches and indicator lights are still retained, and you can still turn on the computer manually in special circumstances.
When using a special pin header (female and male integrated, male header extended), you can connect your original power switch without affecting the original cable.
I prefer that he serves silently on the motherboard so that you ignore his existence, but he does help you.
Use ht7833 to step down.
