Below is an updated project intent that you can add to the project properties. It outlines the design using the ESP32-S3-WROOM-1-N8R8, USB-C 2.0 Receptacle, and CP2102N-A02-GQFN28 for a USB to UART solution, with a regulated 3.3V rail supplied by the AMS1117-3.3. You may update the project description (or project properties) with text like the following:
Design Intent:
Main Processing Module: Utilizing the ESP32-S3-WROOM-1-N8R8 to enable WiFi and Bluetooth connectivity.
Add a 100nF capacitor and a 10µF capacitor between the output of the AMS1117-3.3 and the power input of the ESP32-S3-WROOM-1-N8R8 to ensure proper decoupling.
Place a 100nF capacitor on the VBUS line of the USB-C 2.0 Receptacle for additional filtering.
Resistor Networks:
Include a 56kΩ pull-down resistor on the CC line of the USB-C connector to establish the proper USB-C current configuration.
After updating the project properties with these design considerations, the next step is to add the corresponding schematic passive components. For example:
Add decoupling capacitors (e.g., designate them as [C3] for 100nF and [C4] for 10µF) between the AMS1117-3.3’s output and the power rail feeding the ESP32-S3-WROOM-1-N8R8.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal

Welcome to your new project. Imagine what you can build here.
Properties
Utilize an ESP32-S3 module as the main processing unit, a USB-C connector interfaced with a CP2102 USB-to-UART converter, and an AMS1117-3.3 voltage regulator to provide a stable 3.3V supply to the ESP32. Include necessary passive components: 100nF and 10µF decoupling capacitors at the regulator output, a 100nF capacitor on the USB-C VBUS line, and a 56kΩ pull-down resistor on the USB-C CC line to ensure proper current configuration. Additional resistor networks and capacitor circuits should be implemented as needed for signal conditioning between the USB-C and USB-to-UART converter, and between the regulator and the ESP32.
