ESP32-S3-DevKitM-1_PCB_Design_in_Altium_Designer
I have designed an esp32-s3-devkitM-1 PCB in Altium Designer. Its a four layer PCB where i use ESP32-S3-MINI-1 as main microcontroller. Here, I use 2 USB type-c port , one FTDI Chip for serial communication, one voltage regulator, push button for resetting and booting, one user led , TVS diode and some power led and some resistor and capacitor .

README
Project Highlights:
Designed a 4-layer PCB stack-up to enhance signal integrity and power distribution
Created and customized schematic symbols
Sourced many footprints and 3D model from SnapMagic and Ultra Librarian and also modified some footprint
Explored Differential Pair Routing For high-speed signals
Used a TVS (Transient Voltage Suppression) diode to protect the microcontroller, USB interface, and power lines from sudden voltage spikes caused by ESD events.
Implemented strategic component placement and return path optimization to mitigate EMI issues, carefully planned layout and return paths to reduce noise, and enhanced board-level EMC performance to meet industry standards
