The integration of the PCB board has been completed, and all hardware functions are normal. In fact, the BOM list is already very detailed. If you are not clear about...
Here is the BOM LIST I used, with details updated. Please note that this is the original version by the author, and it is a PCB with unmodified circuits. [ESP32DIV-SHIELD-BOM.docx](https://github.com/user-attachments/files/20256166/ESP32DIV-SHIELD-BOM.docx)...
There are design flaws in ESP32DIV, where pin conflicts cause module initialization failures and stability issues. It is recommended that everyone use it with caution, and we suggest redesigning the...
The code does have parts related to the SD card. Specifically, in the performSDUpdate function within the wifi.cpp file, the SD card is used for firmware updates.
> fixed, its in my fork Well done!
When the USB is connected, the CP2102 and LF33 become extremely hot and even burn out, and the pins of the LF33 emit a beeping sound in the conduction mode...
By the way, the tan capacitor is installed correctly, and the marked side is the positive electrode.
Since it needs measuring and making step-by-step judgments, I can't really help you with this. You should use a multimeter and follow the circuit diagram to check things like resistance,...
It is recommended to use the original CP2102. In addition, the output voltage of pin 3 of LF33 is 3.3V, and pin 1 input voltage is 5V. 
It's still a soldering issue. Try checking the Type-C port.
