KiCad 9: Design an ESP32-S3 IoT 4-layer PCB with sensor and QWIIC interface. Complete Guide.

Thanks PCBWay for sponsoring this video - https://pcbway.com/g/i8683S - Use this link for $5 new user free credit.

Complete step-by-step PCB design process going through the schematic creation, layout, and routing of an
ESP32-S3 Testboard.

The main feautures for this board are:
ESP32-S3 WiFi Module - 8 MB flash
Si7021 high precision temperature and humidity sensor
QWIIC connector
USB-C connector (power / programming)
Buttons for BOOT and RESET
User Button
User RGB LED
2x5 pin SPI bus expansion header
2x3 pin programming header
Power LED on 3.3V rail
For the mechanical side of things we have:
4 x 3.2mm mounting holes
Size 50x50mm
4 layer board design
