USB-C PD board with ESP32-S3

Browse Source 
Complete initial design:
- CH224K PD sink controller (custom corrected symbol)
- USB-C receptacle (16-pin USB2.0)
- P-Channel MOSFET VBUS switch
- LD1117S33 3.3V LDO regulator (800mA)
- ESP32-S3-WROOM-1 module
- 15 nets: VBUS, VOUT, 3V3, GATE, CC1/CC2, USB_DP/USB_DN
- 5.1kΩ CC pull-down resistors
- CFG1/CFG2 for PD voltage selection
- Input/output decoupling capacitors
