The schematic is as above;
The layout is as above
The analog part uses magnetic bead filtering. HWCFG uses a single 3V3 power supply configuration. The buck circuit formed by the classic BSL215 steps down 1V3 to supply VDD. The power supply uses a pmos anti-reverse connection design for the 5V input, and a voltage regulator tube is added to prevent overvoltage. But generally 3V3 power supply is enough, there is no need to use 5V power supply
Personally, I think the design is quite satisfactory, that’s all.
The project is designed using KICAD and is placed in the attachment.
