I’ve completed the removal of the USB-C connector and its power circuitry while preserving the USB data nets.
Work done
- Removed all USB-C connector symbols and USB power path components.
- Severed VBUS-to-+5 V nets; removed ESD/TVS diodes and decoupling capacitors.
- Cleared orphaned net labels and resolved all ERC/DRC warnings.
- Preserved and reconnected U1 USBD+ and USBD− pins to their nets.
Success criteria review
- ✅ All USB-C and USB-derived power components removed
- ✅ D+ and D− nets remain intact and properly connected
- ✅ No ERC or DRC warnings remain
Next step
Proceed to a final schematic review for completeness and then move on to preparing the PCB layout (footprint review and stackup configuration).

To create a high-level block diagram for the ESP32 DEV Kit template project featuring two HC-SR04 ultrasonic sensors and several connectors, and incorporating the manufacturer part numbers where applicable, you can use the Mermaid syntax. The Mermaid diagram described below will outline the major components and their interconnections, based on the provided project details.
Image
- This diagram represents the ESP32-DEVKIT-V1 as the central processing unit, connecting to various components.
- Each block includes the designator and the manufacturer part number (MPN) where available. For the HC-SR04 ultrasonic sensors (US1 and US2) and connectors (J1 to J6), MPNs and designator prefixes are offered along with the manufacturer's name.
- Connections between the ESP32 and other components are shown using the pin connections detailed in the project description. For simplicity, direct lines represent these connections, with labels indicating the ESP32's pin used.
- The connection from the HC-SR04 ultrasonic sensor (US1) to the ESP32 is indicated generally without specific pin details due to the provided information not detailing specific interfacing pins beyond US2's connection.
This diagram offers a high-level overview, useful for understanding the project's major components and their connections.

create a detailed step by step plan table for U1 to verify its functionality.
1y
Creating a detailed step-by-step plan to verify the functionality of the ESP32 DEVKIT V1 (U1) involves several key procedures encompassing hardware setup, firmware programming, and functionality tests. Here's a structured approach:
Step 1: Initial Setup and Power Verification
-
Assemble Necessary Tools and Equipment
- ESP32 DEVKIT V1 (U1)
- USB cable for programming
- Computer with the ESP-IDF or Arduino IDE installed
- Multimeter
-
Connect U1 to your Computer
- Use a USB cable to connect U1 to the computer.
-
Check Power Supply
- Verify that U1 is correctly powered by checking the 3.3V and GND pins with a multimeter.
-
Open the Arduino IDE
- Launch Arduino IDE on your computer.
-
Select the ESP32 Board
- Go to Tools > Board and select "ESP32 Dev Module".
-
Load the Blink Example
- Navigate to File > Examples > 01.Basics and open the "Blink" sketch.
-
Set the Correct COM Port
- Select the correct COM port from Tools > Port.
-
Upload the Sketch
- Click the Upload button to program U1 with the blink sketch.
-
Connect LED to IO Pin (e.g., D2)
- Connect an external LED through a current limiting resistor (e.g., 330Ω) to D2 and GND. Assumption: For the blink sketch, you can modify it to blink D2 or simply use an IO pin like D2 which is connected as follows:
- Connect U1:D2 to one end of the resistor.
- Connect the other end of the resistor to the anode of the LED.
- Connect the cathode of the LED to U1:GND.
- Connect an external LED through a current limiting resistor (e.g., 330Ω) to D2 and GND. Assumption: For the blink sketch, you can modify it to blink D2 or simply use an IO pin like D2 which is connected as follows:
-
Verify Blinking
- Upon successful upload, the LED should start blinking. If it does, it means U1 is correctly programmed and the IO pin is functioning.
-
Upload Echo Program
- Modify or upload a simple echo program that reads serial input and echoes it back.
-
Open Serial Monitor
- In the Arduino IDE, open the Serial Monitor.
-
Test Serial Echo
- Type something into the Serial Monitor and press send. Verify that the ESP32 echoes back the typed message.
-
Load Wi-Fi Example Sketch
- Use an example Wi-Fi sketch from the IDE (e.g., Wi-Fi scan) and upload it to U1.
-
Monitor Serial Output
- Open the Serial Monitor to view the Wi-Fi networks detected by ESP32.
Verification Summary Table
| Step | Task | Expected Outcome |
|---|---|---|
| 1 | Connect U1 to Computer and Check Power | 3.3V across power pins; Device powers on |
| 2 | Load and Upload Blink Sketch | Successful compilation and upload |
| 3 | Verify IO Pins Functionality | External LED blinks |
| 4 | Serial Communication Test | Echoed message matches input |
| 5 | Wi-Fi Test (If Applicable) | Wi-Fi networks are listed in Serial Monitor |
Note: Adjust the verification plan according to the functionality you wish to test on the ESP32 DEVKIT V1, including additional features you might be utilizing in your project.

- Objective: Ensure all components receive the correct operating voltage.
- Steps:
- Verify the output of V1 (Voltage Source) is stable at 5V.
- Measure the output voltage of U2 (L7805CV) and U3 (LM7805CT/NOPB) to ensure they are providing a regulated 5V output.
- Check that the ESP32 DEVKIT V1 (U1) receives 3.3V at its 3V3 pin and 5V at its VIN pin, confirming voltage regulation from 5V to 3.3V onboard is functional.
Step 2: Basic Connectivity Check- Objective: Confirm that all components are correctly soldered and that there are no short circuits.
- Steps:
- Perform a continuity test on all GND connections to ensure they are common and have no breaks.
- Use a multimeter to check for unintended connections between VCC and GND across the project to identify any potential short circuits.
Step 3: Component-Specific Verification-
Objective: Test the functionality of individual components.
-
Sub-Objective 1: ESP32 DEV KIT V1 (U1)
- Upload a simple blink sketch to verify basic programming and GPIO functionality.
- Test serial communication over USB to ensure the microcontroller can send/receive data.
-
Sub-Objective 2: HC-SR04 Ultrasonic Sensors (US1 & US2)
- Connect US1 and US2 to U1 as per the project nets and upload a distance measurement sketch.
- Verify that both sensors are emitting pulses and measuring distances accurately by observing serial output.
-
Sub-Objective 3: Power Connectors (J1, J2, J3, J4, J5, J6)
- Ensure that each power connector properly routes power to its designated net without voltage drops.
Step 4: Integration and Full System Test- Objective: Confirm that the system functions as intended when operating together.
- Steps:
- With the ESP32 programmed for a specific application involving HC-SR04 sensors (e.g., distance measurement, object detection, etc.), verify the system performs as expected in a real-world scenario.
- Monitor the serial output for any errors or unexpected behavior, adjusting the code or hardware setup as necessary.
Step 5: Debugging and Troubleshooting
