Let me take a look at your project.
Here are some observations and suggestions:
  1. Capacitor Values: I notice that several capacitors, such as C17, C3, C1, and others, have their capacitance property unspecified. Make sure to define these values based on your application's requirements.
  2. Pin Connections:
    • Ensure that all critical connections are accurately made. For example:
      • The ACS712 sensors (U1, U2, U3, and U4) should have their VCC and GND pins connected appropriately.
      • Verify the connections made to ESP32 (U5), especially power inputs and communication pins.
  3. Power Supply:
    • Double-check that the power inputs are correctly mapped and ensure the ESP32 and other devices receive the right voltage levels. VIN should be provided a reliable voltage source suitable for the device.
  4. Unused Pins:
    • Check if any other components with unused pins need to be connected, especially for ICs that may require certain pins to be tied High/Low.
  5. Signal Integrity:
    • Consider adding decoupling capacitors near the power pins of ICs for improved signal stability.
  6. Component Placement:
    • The design seems to refer to a shield form-factor—consider the physical layout to ensure proper fitment if using existing headers or mounting holes.
These points focus on critical areas often needing attention. Let me know if there's any part of the design you want to delve into more deeply!

To verify the functionality of the ESP32-DEVKIT-V1 (designator U5), we'll create a step-by-step plan. This plan will help in testing basic functionality, I/O pins, and other features of the ESP32. Here's the table:

Table

StepDescriptionProcedureExpected Result
1Power UpConnect U5:VIN to +5V and U5:GND to Ground.Device powers on, and the onboard LED may blink if programmed.
2ProgrammingConnect U5:TX0 to USB-to-Serial adapter RX, RX0 to USB-to-Serial adapter TX. Upload a "Blink" sketch using the Arduino IDE.The onboard LED should blink.
3Wi-Fi FunctionalityLoad and run a basic Wi-Fi scan sketch to list available networks.Output should display available Wi-Fi networks.
4GPIO TestingConfigure GPIO pins (U5: D2, D4, D5, etc.) as inputs/outputs in a sketch and test with LEDs or buttons.GPIO pins should control LEDs or read buttons correctly.
5ADC FunctionalityConnect a variable voltage source to VP or VN, run an ADC read sketch.ADC readings should reflect the input voltages.
6I2C CommunicationConnect an I2C device (e.g., an OLED display) to D21 (SDA) and D22 (SCL), run an I2C scan sketch.The I2C address of the connected device should be detected.
7Serial CommunicationOpen Serial Monitor in Arduino IDE after loading a sketch that uses Serial communication.Text sent from ESP32 should appear in the Serial Monitor and vice versa.
8PWM OutputAttach an LED to a PWM-capable pin (e.g., D5) and run a PWM sketch to fade the LED.The LED should smoothly change its brightness.
9SPI CommunicationConnect an SPI device (e.g., an SD card module) to the designated SPI pins, load an SPI test.The ESP32 should communicate with the SPI device, e.g., read/write operations.
10Deep Sleep ModeLoad a sketch that puts ESP32 into deep sleep, and wake it using a button connected to an RTC GPIO.The ESP32 should enter sleep, reducing power consumption, and wake on button press.
Follow these steps systematically to verify the full functionality of the ESP32-DEVKIT-V1. Let me know if you need further details on any of the steps!

The component U1 in your project is an ACS712ELCTR-20A-T, which is a current sensor IC from Allegro MicroSystems. This sensor is capable of measuring both AC and DC currents. Here’s a breakdown of its function:
  • Current Sensing Capability: It can measure the current flowing through your circuit up to ±20A. The sensor provides an analog voltage output that is proportional to the current.
  • Isolation: The ACS712 provides electrical isolation between the current it is measuring and the sensor's output. This is beneficial for safety and protecting your microcontroller, such as the ESP32-DEVKIT-V1 you have in the project.
  • Output: The output voltage at the VIOUT pin is a linear representation of the current flowing through the IP+ and IP- pins. When there is no current flowing through the sensor, the output voltage is approximately half of the supply voltage VCCVCC.
  • FILTER Pin: The FILTER pin allows you to connect a capacitor to set the bandwidth of the device, which can help reduce noise in your current measurements.
This sensor is commonly used for power monitoring applications such as solar stations, as in your project. If you have any specific questions about how to connect or use U1, feel free to ask!

Let’s go through the key aspects of your project to identify any potential issues:
  1. Component Values:
    • There are several capacitors (e.g., C1, C2, C3) without specified capacitance values. Ensure that these values are determined based on your application requirements.
  2. Power Supply Connections:
    • Check the power connections for U5 (ESP32-DEVKIT-V1). Ensure the 3V3 pin is connected to an appropriate voltage supply if needed.
    • Ensure that the ACS712 sensors (U1, U2, U3, U4) have their VCC connected to a stable +5V source.
  3. Ground Connections:
    • Review the GND net to make sure that all components needing a ground reference are properly connected to the ground net.
  4. Unused Pins:
    • For U6, there are two pins labeled as GND. Make sure both ground pins are connected unless specified otherwise by the datasheet.
  5. Net Connections:
    • The nets like ADC_1, ADC_2, ADC_3, and ADC_4 are connected to ESP32 analog pins. Verify the pin mappings are as intended for the signals you need to measure.
  6. Overlapping Nets/Designators:
    • ADC_1 and other ADC nets are repeated, ensure there’s no confusion or unintentional overlap in the net names or connections.
By addressing these checks and ensuring that your schematic logic is sound, you can avoid potential issues when your PCB is populated and tested. Let me know if there's any specific part of the circuit you'd like to discuss further!
