I noticed a few areas that could potentially cause issues in your ESP32-based control board project:
  1. Duplicate Designators: It seems that there are duplicate designators like (MotorA_IN1), which could cause confusion or errors in the schematic or PCB design. Make sure each component has a unique designator.
  2. Unspecified Capacitance: For capacitors (C2), (C1), and (C3), the capacitance is not specified. Defining these values is crucial for the stability and functionality of power supply circuits.
  3. Obsolete Part: The (7805) voltage regulator is marked as obsolete. You might want to consider replacing it with a similar part that is still in active production.
  4. Unconnected Nets/Components: Check that all essential components and nets are correctly connected, especially power and ground connections, to avoid incomplete circuits.
  5. Duplicate Net Names: Ensure there's consistency in net naming and that duplicates are intentional, e.g., different designators associated with the same net.
Ensure these issues are addressed for a more reliable design. If you have any specific questions or need further assistance, feel free to ask!

would U1 work properly if the EN pin is connected like this?

In your project, the EN (Enable) pin of U1 is connected to the GND net. This would typically disable the ESP32-DEVKIT-V1 since the EN pin is an active-high input. To ensure that the ESP32 works properly, the EN pin should be pulled high (e.g., connected to VCC) to enable the module.
Recommendation:
  • Connect U1:EN to a high voltage level, such as U1:3V3, instead of GND.
Let me know if you would like further assistance on setting up the connections properly!
